True False The current induced in a copper wire coil by a changing magnetic fiel

Question

True False The current induced in a copper wire coil by a changing magnetic field is proportional to the number of turns in the coil..

True False If the rate of change of magnetic field within a coil of wire is constant, the EMF is constant.

True False An Amperian loop which is tangential to a magnetic field line will always encircle a current.

True False The induced electric field lines always begin and end on charges.

True False The magnetic field due to a current element is proportional to the inverse square power of the radial distance to the current element.
