A long straight wire carries a current I1 = 3.2 A and is a distance h = 12.2 cm from a rectangular current loop that carries a current I2 = 1.2 A. If the loop has a lengthL = 42 cm and a width w = 17 cm, what is the magnitude of the force exerted by the wire on the loop?
What is the force exerted by the current loop on the wire?
A 2 kg object attached to a spring moves without friction (b = 0) and is driven by an external force given by the expression F = 4.60sin (2pi*t), where F is in newtons and t is in seconds. The force constant of the spring is 20.0 N/m.
