When an $$AC$$ signal of frequency $$1kHz$$ is applied across a coil of resistance $$100\Omega$$, then the applied voltage leads the current by $$45^o$$. The inductance of the coil is:

Study involving both electricity and magnetism is called ______.

A conducting ring of radius $$r$$ and resistance $$R$$ rolls on a horizontal surface with constant velocity $$v$$. The magnetic field $$B$$ is uniform and is normal to the plane of the loop. Choose the correct option.

A metal rod moves at a constant velocity in a direction perpendicular to its length. A constant uniform magnetic field exists in space in a direction perpendicular to the rod as well as its velocity. Select the correct statement(s) from the following:

A conductor $$AB$$ of length $$l$$ moves in x-y plane with velocity $$\vec { v } ={ v }_{ 0 }\left( \hat { i } -\hat { j }  \right) $$. A magnetic field $$\vec { B } ={ B }_{ 0 }\left( \hat { i } +\hat { j }  \right) $$ exists in the region. The induced emf is

A magnetic field of flux density 1.0 Wb $$m^{-2}$$ acts normal to a 80 tum coil of 0.01 $$m^2$$ area. The e.m.f. induced in it, if this coil is removed from the field in 0.1 second is :

Constant magnetic field in the coil induces _________ current in it.

According to Faraday's law, the total charge induced in a conductor that is moved in a magnetic field depends upon:
