Suppose I have a circular loop of wire with radius R. I run a current I through the loop and measure a magnetic field B at the center of the wire. If I double the radius of the wire and triple the current in the wire, what is the new magnetic field at the center of the wire

Electromagnetic induction. a coil of wire contains n turns and has an electrical resistance r. the radius of each turn is a. initially, inside the coil there exists a uniform magnetic field of magnitude b0 parallel to the axis of the coil. the magnetic field is then reduced slowly. the current induced in the coil is i. how long does it take for the magnitude of the uniform field to drop to zero?
