Assertion: Iron filings are kept near a magnet it gets arranged in a particular fashion.
Reason: Magnetic field is a scalar quantity
Both assertion and reason are correct and reason is the correct explanation of assertion.
Both assertion and reason are correct, but reason is not the correct explanation of assertion.
Assertion is true, but reason is false.
Assertion is false, but reason is true.

Magnetic field is not a scalar quantity rather it is a vector quantity which has both magnitude and direction. So, when iron filings are placed around a magnet, they get arranged in a fashion similar to that of magnetic lines. Thus, assertion is correct, but reason is false.
Assertion: A current carrying rod is suspended between U-shaped magnet, the rod deflects.
Reason: A force is exerted on the rod due to magnetic field.
Both assertion and reason are correct and reason is the correct explanation of assertion.
Both assertion and reason are correct, but reason is not the correct explanation of assertion.
Assertion is true, but reason is false.
Assertion is false, but reason is true.

A force is always exerted due to magnetic field in the same way electric current flowing through any conductor produces magnetic field. And in this case, Fleming’s left-hand rule is used to predict directions of the magnetic field, current and displacement. Thus, assertion and reason both are correct and reason is the correct explanation of assertion.
Assertion: The energy of charged particle moving in a uniform magnetic field does not change.
Reason: Work done by magnetic field on the charge is zero.
Both assertion and reason are correct and reason is the correct explanation of assertion
Both assertion and reason are correct, but reason is not the correct explanation of assertion.
Assertion is true, but reason is false.
Assertion is false, but reason is true.
(1)
The force on a charged particle moving in a uniform magnetic field always acts in direction perpendicular to the direction of motion of the charge. As work done by magnetic field on the charge is zero, so the energy of the charged particle does not change. Thus, both assertion and reason are correct and reason is the correct explanation of assertion.
Assertion: A current carrying conductor experiences a force in a magnetic field.
Reason: The net charge on a current carrying conductor is zero.
Both assertion and reason are correct and reason is the correct explanation of assertion.
Both assertion and reason are correct, but reason is not the correct explanation of assertion.
Assertion is true, but reason is false.
Assertion is false, but reason is true.
(2)
When a current carrying conductor having no net charge is placed in a magnetic field, the free electrons of the conductor move towards the positive end of the conductor with same drift velocity, hence a magnetic force acts on them. The positive ions of the conductor being stationary, do not experience any magnetic field. Thus, both assertion and reason are correct but reason is not the correct explanation of the assertion.
Assertion: Magnetic field lines do not intersect each other.
Reason: It is impossible to have two direction of the magnetic field at a point.
Both assertion and reason are correct and reason is the correct explanation of assertion.
Both assertion and reason are correct, but reason is not the correct explanation of assertion.
Assertion is true, but reason is false.
Assertion is false, but reason is true.
(1)
Magnetic field lines do not intersect, because it happen so then at that point two direction of magnetic field lines exist, which is not possible. Thus, both assertion and reason are correct and reason is the correct explanation of the assertion.
Assertion: The principle of electromagnetic induction was discovered by Michael Faraday
Reason: The principle is used only in DC generators.
Both assertion and reason are correct and reason is the correct explanation of assertion.
Both assertion and reason are correct, but reason is not the correct explanation of assertion.
Assertion is true, but reason is false.
Assertion is false, but reason is true.
(3)
Not only DC generators but AC generators also work on the principle of electromagnetic induction. Thus, assertion is true, but reason is false.
Assertion: Electric Motor converts electric energy into mechanical energy.
Reason: Electric Motor is based on the principle of Fleming's right hand rule. Thus assertion is true, but reason is False.
Both assertion and reason are correct and reason is the correct explanation of assertion.
Both assertion and reason are correct, but reason is not the correct explanation of assertion.
Assertion is true, but reason is false.
Assertion is false, but reason is true.
(3)
Electric motor is based on the principle of Fleming's left hand rule. Thus assertion is true, but reason is false.
Assertion: A compass is kept near a wire carrying current gets deflected.
Reason: Electric current is capable of producing a magnetic effect.
Both assertion and reason are correct and reason is the correct explanation of assertion.
Both assertion and reason are correct, but reason is not the correct explanation of assertion.
Assertion is true, but reason is false.
Assertion is false, but reason is true.

Here while carrying out an experiment if a compass needle is placed near a wire carrying current then due to the effect of magnetism which is produced due to electric current produced in the wire the needle gets deflected. It shows that the magnetism and electricity are interlinked. Thus, both assertion and reason are correct and reason is the correct explanation of assertion.
Assertion: Deflection of the iron filings changes when current in the conductor varies.
Reason: Magnitude of the magnetic field does not change with the magnitude of current.
Both assertion and reason are correct and reason is the correct explanation of assertion.
Both assertion and reason are correct, but reason is not the correct explanation of assertion.
Assertion is true, but reason is false.
Assertion is false, but reason is true.
(3)
As the current changes in the conductor, magnitude of the magnetic field produced also varies which is the reason for a change in the deflection of the iron filings. Thus assertion is true, but reason is false
Assertion: Galvanometer is used to measure polarity.
Reason: Galvanometer is an instrument which is used to detect current in any circuit.
Both assertion and reason are correct and reason is the correct explanation of assertion.
Both assertion and reason are correct, but reason is not the correct explanation of assertion.
Assertion is true, but reason is false.
Assertion is false, but reason is true.
(2)
In testing purposes galvanometer is used to measure polarity. There is a torque acting on a current carrying coil suspended in a magnetic field which produces deflection. Deflection is directly proportional to current flowing through the galvanometer coil. Thus, both assertion and reason are correct but reason is not the correct explanation of the assertion.
