Where is the diagram
On the diagram below, draw the magnetic field pattern around a long straight current-carrying conductor. The diagram below shows a coil consisting of two loops of wire The coil is suspended vertically Each loop has a diameter of 6.0 cm and the separation of the loops is 0 20 cm. The coil forms part of an electrical circuit so that a current may be passed through the coil. State and explain why, when the current is switched on in the coil, the distance between the two loops changes. When there is a current I in the coil, a mass of 0.10 g hung from the free end of the coil returns the separation of the loops to the original value of 0 20 cm. The circumference C of a circle of radius r is given by the expression C = 2pir. Calculate the current I in the coil. You may assume that each loop behaves as a long straight current-carrying wire.
