Suppose the magnetic field changes uniformly from $0\mathrm{.}404$ T to $0\mathrm{.}295$ T in the next $0\mathrm{.}578$ s$.$

$($a$)$ Compute the induced emf in the coil.

$=$

What factors affect the emf induced in a loop when the magnetic field through that loop changes? V

$($b$)$ Compute the induced current.

I $=$

The magnitude of any quantity is always positive. A counterclockwise as viewed from above the coil
