Question
Indicate true or false in each of the following statements:
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.
Explanation / Answer
1. T, check formula 2. F emf induced is equal dphi/dt. phi= BA. 3. T 4. T, for positive charges, F for negative 5.T, check formula
