A square single turn wire loop 1.0 cm on a side id placed inside a solenoid that has a circular across section of radius 3.00 cm . The solenoid is 20.0 cm long and wound with 100 turns of wire. a) if the current in the solenoid is 3.00 A find the flux through the loop. b) if the current in the solenoid is reduced to zero in 3.00 s fine the magnitude average induced emd in the loop
