When a non magnetic metallic strip is moved away from between the poles of a horse-shoe magnet, there is

Between dissimilar poles of the magnet there is-

When a small piece of wire passes between the magnetic poles of a horse-shoe magnet in 0.1 sec, emf of 4 xx 10^(–3) volt is induced in it. The magnetic flux between the poles is :

Figure shows three different orientations of a circular coil rotating in the magnetic field between the poles of a horse shoe magnet. Determine the direction of induced current in the coil, if the rotation is anticlockwise as viewed by the reader.

Figure shows three different orientations of a circular coil rotating in the magnetic field between the poles of a horse shoe magnet. In which orientation during rotation with uniform angular speed) is the induced e.m.f. greatest?

Why has the magnet a horse-shoe shape?

When a magnetic is moved with its N pole away from the coil, then the nearer face of the coil behaves as a

The force acting on a north pole of magnet of pole strength 3200 Am and 10 cm away from the south pole of a point bar magnet of pole strength 40 Am is .......... N.
