Assertion: If a unit north pole rotates around a current carrying wire then work has to be done.
Reason: Magnetic field produced by current is always non - conservative in nature.

View answer and explanation

Correct option: A

If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion

Option A is correct because the work done in moving a unit north pole around a current-carrying wire is non-zero, and this is due to the non-conservative nature of the magnetic field produced by the current.

The magnetic length of a bar magnet is 15 cm then its geometric length is If area vector

\vec A = 2\vec i - 3\vec j + 6\vec k\,{m^2}

flux density vector

\vec B = - 3\vec i + \vec j + 2\vec k\,\left( {Wb/{m^2}} \right)

. Then magnetic flux linked with the coil is [Wb] The area of hysteresis loop of a material is equivalent to

250\;joule

10\;kg

material is magnetized by an alternating field of

50\;Hz

then energy lost in one hour will be (density of material is

7.5\;gm/c{m^3}

) A bar magnet of moment

M

is placed in the magnetic field

B

. The torque acting on the magnet is Assertion(A): Earth's magnetic field inside a closed iron box is less as compared to the out side.

Reason(R): The magnetic permeability of iron is low. Force between two identical short bar magnets whose centers are

r

metre apart is 8.1 N, when their axes are along the same line. If separation is increased to 3

r

and the axis are rearranged perpendicularly, the force between them would become
