Question

True or False?

1. 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.
2. An arbitary shaped Amperian loop through which no currents pass will never pass through a magnetic field.
3. If the rate of change of magnetic field within a coil of wire is constant, the EMF is constant.
4. The magnetic field due to a current element is proportional to the inverse square power of the radial distance to the current element.
5. Induced electric field lines are continuous, i.e. having no beginning or ending points.
