For a long conducting wire, the magnetic field induced by the current is strongest A.on the surface of the wire. B.in the interior of the wire. C.some fixed perpendicular distance away from the wire.

A current carrying conductor in a vacuum will always create the environment which will maximize the strength of the generated magnetic field. A.True B.False

In order for a magnet to induce a current in a coil, A.the magnet and coil must be held stationary B.the magnet should be moved towards the coil. C.the magnet should be moved away from the coil. D.Either of B or C.

To compute magnetic flux, we must A.define a surface through which the magnetic field lines pass. B.know the strength of the magnetic field C.know the direction of the magnetic field on the surface. D.All of the above.

If a surface is perpendicular to magnetic field lines, the strength of the magnetic field is simply the ratio of the magnetic flux to the area of the surface. A.True B.False

The magnitude of an induced emf in a circuit depends on the number of identical turns in the circuit A.True B.False
