Magnet Science Project Idea
How magnets are used.; The current of electricity passing through the coil of wire gives the iron rod around which it is wound the power of a magnet.; This kind of magnet is temporary, possessing its power only when the current of electricity is passing through the wires.; For this reason it [...]

This drawing shows a left hand with the thumb, pointer, and middle finger sticking out. The thumb is labeled 'motion', the pointer is labeled 'field', and the middle finger is labeled 'current'.This animation shows a loop of wire rotating clockwise in a static magnetic field that has a north pole on the left and a south pole on the right. The battery is connected to the rotating loop with the positive terminal on the right.This drawing shows circular loops of wire with knots and axles in the 3 o'clock and 9 o'clock position where the loops are bound.This shows a circular coil with axles extending from it in the 3 o'clock and 9 o'clock positions. The top half of the axles are stripped of insulating material exposing the bare copper beneath.Diagram of a Beakman motor

Objective
To learn how to build a simple electric motor and to determine which motor design produces the fastest rate of spin.
Introduction
So, what do windshield wipers, CD players, VCR’s, blenders, ice makers, computers, and talking toys have in common? They all contain electric motors! In fact, if you walk through your house, it is possible to [...]
