The DC current from a battery will create a flow of electrons in the same direction. So the wire carrying a DC current will have a small magnetic field around it. Coiling the wire concentrates the magnetic field inside the coil. Whatever is placed inside this coil will then be in a stronger magnetic field than if the wire was uncoiled.
b) Make a graph of the current in the coil on the right plot below. Make sure to indicate numerical values and explain your choice of sign for the current. Solution. a) The magnetic field for a solenoid is (B=dfrac{mu_oIN}{L}). The maximum current with be when the magnetic field is at 0.2 T, since the current is reduced with time:
Electrons moving along a wire make a magnetic field that goes in circles around the wire. When you bend the wire into a coil, the magnetic fields around each loop of the coil add up to make a long, thin magnet with north at one end and south at the other. The more loops the coil has, the stronger the magnetic field, while the current is flowing.
Series 200 and 400 stainless steel do not have nickel, are naturally magnetic and can be magnetized. Using simple methods of magnetizing metal produces only a temporary magnet. To permanently magnetize something, you need a large alternating-current magnetic coil, which is not generally available in most homes.

You might have noticed that your motor did not work if the wire only touched the tip of the battery but not the magnet. In order for electrical current to flow, you need a closed circuit. That means the wire needs to be touching on both ends at the same time. If it only touches on one end, you have an open circuit, and no current will flow.
