Question
Indicate true or false in each of the following statements:
T or F: The magnetic field due to a current element is proportional to the inverse third power of the radial distance to the current element.
T or F: An Amperian loop which is tangential to a magnetic field line will always encircle a current.
T or F: A flat wire loop is lying in the same plane as a long straight wire. The current in the straight wire is changing as a function of time and therefore the induced electric field in the wire loop is uniform.
Tor F: The negative sign in Faraday's Law (Lenz's Law) would completely eliminate any change in magnetic field within a superconducting coil.
T or F: The magnetic flux passing through a flat coil is measured by counting the number of field lines passing through the inside of the coil only.
