Learning Task No. 1: Directions: Write YES on the blank if the statement is correct and write NO if the statement is incorrect.

1. Electromagnets are simple devices that mimic the behaviour of natural magnets.

2. As the electrical current moves around the loops of the coil, it generates a magnetic field like that of a small bar magnet.

3. Changing the metal core for a different metal will make the electromagnet stronger or weaker.

4. The greater the current in the coil, the stronger the magnetic field will grow.

5. Using different types of metal wire will also affect the field strength Learning


Task No. 2: rection: Write True if the statement is correct and False if the statement is wrong.

1. Magnets can attract or pull things like pins, needled and metals, and its force is called magnetism.
2. Spoons, needles, coins and nails and other metal can be pulled by magnets. 3. Electromagnet is the area around the magnet which exerts force.
4. One of two points in a magnet where its magnetism is strongest is called magnetic poles.
5. Electromagnet is a temporary magnet.
