I. Purpose:

To determine what is a motor, parts and to determine how it works.

II. Materials:

Armature Scissors Battery

Copper Wire

Safety Pins

Tape

U-Shaped Magnet

III. Procedure:

1. Prepare a Battery (1.5 volts) and put 2

Safety Pins at both terminals of the

battery.

2. Also, prepare an Armature, a Copper Wire looped and tied at both

ends.

3. After preparing procedure number 1 and number 2, insert the ends

of the Armature to the holes of the Safety Pins attached in the dry

cell.

4. Finally, place the dry cell and armature on a U-shaped magnet.

Observe what happens.

IV. Observation:

As we observed the Electromagnetic Swing placed on the magnet, the

Armature moves and rotates faster with the South Pole at the top and

the North pole at the bottom and vice versa.

V. Conclusion:

After conducting the activity, we concluded that a motor. An electric

motor is all about magnets and magnetism: A motor uses magnets to create

motion. A simple motor consists of the armature, commutator, brushes, axle,

field magnet and a dry cell or other source of power. A coil of wire in a magnetic

field rotates continuously as long as it carries current. The rate of the motor's

rotation depends on the force of the armature. The length of armature may be

increased by having more loops.
