A bird is in a wire cage hanging from a spring balance.Is the reading indicated on the balance,when the bird is flying out in the cage greater than ,less than or the same as that when the bird is sitting in the cage ?Explain.

A current balance is a device to measure magnetic forces. It is constructed from two parallel coils, each with an average radius of 12.5 cm. The lower coil rests on a balance, it has 20 turns and carries a constant current of 4.0 A. The upper coil, suspended 0.314 cm above the lower coil, has 50 turns and a current that can be varied. The reading of the balance changes as the. magnetic force on the lower coil changes. What current is needed in the upper coil to exert a force of 1.0 N on the bottom coil?
