... Though the net force on a loop of wire in a uniform magnetic field is always zero, a magnetic field can exert torque on a loop of wire. This is given by the equation: t t‚B 7t œ . t is called the magnetic moment. It is defined as follows.: The vector . t is ME, where M is the current, and E is the a ...

PaperClip Motor
... GOAL: Today’s activity is to build and operate a paper clip motor. Motors are a main component in mechanical systems, which are often used due to their simplicity, efficiency and ease of integration. Today, we can see motors in hybrid cars, pencil sharpeners and toys. While motors have only been aro ...

Lesson 1: Magnets have 2 poles. Like poles attract, unlike poles
... Magnets have 2 poles. Like poles attract, unlike poles repel. Magnets attract iron. Magnetic force is strongest around the poles of a magnet. Vocab: magnet Magnetism Magnetic pole Magnetic force Lesson 2: Magnetic fields spread out from one pole to the other. They are curves lines that never cross. ...
