When current is passed through it, does the coil tend to lengthen, shorten, or stay the same length? O The coil tends to stay the same length. O The coil tends to lengthen. O The coil tends to shorten. O The answer depends on the current direction.

According to Lorentz force law, if the current direction and the external magnetic field direction are such that they tend to oppose each other, the coil shortens but the coil tends to lengthen if the current direction and the external magnetic field direction reinforce each other.
