An inductor and a resistor are placed in a circuit with an
ammeter, a switch and a battery of emf ε=22.0 V. The switch
closes at 0.00s and when the time reaches 1.25 s, the ammeter reads
0.200 A. If the resistance is 40 Ω, determine the magnetic energy
(J) stored by the circuit when t=3.50s. Give answer in J and to two
places to the right of the decimal.
