He should a step-up transformer with k=220/120=1.83 so output coil must have 240*1.83=440 turns
Answer:
Y
Explanation:
Y will produce the strongest magnetic force because the current intensity is medium and it has 50 turns in the wire. the number of turns will increase the force because the magnetic field will be more concentrated.
Have a great day :)
