Right Hand Rule Practice
... Right Hand Rule Practice Right Hand Rule #1: Moving Charge An electron moving in a uniform magnetic field will travel in a circle. Using the right hand rule, show that this is true. Make eight “measurements” (N, NE, E, SE, S, SW, W, NW). At the location of each measurement, draw one arrow that shows ...

... Lenz’s Law tells us that an induced current always flows in a direction that opposed the change that caused it. For example, pushing a magnet towards a conducting ring makes them repel, but bringing the magnet away from the ring makes the ring attracted to the magnet. When dropping a rod in the vert ...

Electromagnet
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off. Electromagnets usually consist of a large number of closely spaced turns of wire that create the magnetic field. The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagnetic material such as iron; the magnetic core concentrates the magnetic flux and makes a more powerful magnet.The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the winding. However, unlike a permanent magnet that needs no power, an electromagnet requires a continuous supply of current to maintain the magnetic field.Electromagnets are widely used as components of other electrical devices, such as motors, generators, relays, loudspeakers, hard disks, MRI machines, scientific instruments, and magnetic separation equipment. Electromagnets are also employed in industry for picking up and moving heavy iron objects such as scrap iron and steel.
