IF the current in the coil is in clockwise then what would be the face of the coil?

IF the current in the coil is in anti-clockwise then what would be the face of the coil?

If the current in a coil as observed is anticlockwise, then that face of the coil would become __________pole.

The mutual inductance between two coils is 0.5 H .It the current in one coil is changed at the rate of 5 A//s ,what will be the emf induced in the other coil?

The mutual inductance between two coils is 0.5 H .It the current in one coil is changed at the rate of 5 A//s ,what will be the emf induced in the other coil?

A large circular coil of radius R and a small circular coil of radius r are put in vicinity of each other. If coefficient of mutual inductance of this pair equals 1 mH, what would be the flux linked with larger coil when a current of 0.5 A flows through the smaller coil? When would current in the smaller coil falls to zero, what would be its effect in the larger coil ?

The number of turns in the primary and secondary coils of an ideal transformer are 140 and 280, respectively. If the current through the primary coils is 4 A, what will be the current in the secondary coil?

The number of turns in primary and secondary coils of a transformer is 50 and 200 respectively .If the current in the primary coil is 4 A then the current in the secondary coil is
