Magnets

Science Club  - Class 5

 

Magnetic_Field_Lines

Magnets are objects with a magnetic field.

 

Magnets have opposite poles.

A north pole and a south pole.

 

Unlike poles attract each other.

Like poles repel each other

Activity #1

  Magnetized Paper Clip Chain

Science Club  - Class 5

Magnets and Electricity

 

A magnetized paper clip chain shows how magnetism can be created by induction. That means an object can become magnetized itself if it is placed next to a magnetized object.

 

How one paper clip in the chain magnetizes the next?

electric_line         What is Electricity?

Electricity is the movement of electrons.

 

 

Electricity has positive and negative charge just like a magnet has poles.

 

Rubbing a balloon on your head will give the balloon a negative charge because it picks up electrons from your hair.
