Magnets!
By: Madi Rozeboom
What is a magnet?
- A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets.
Magnetic Forces
The force exerted between two magnets or magnetic materials.
Magnet Use 1
Compasses have to have magnets because they point to the North and South pole.
Magnet Use 2
Magnets are used in machines like this MRI scanner because the magnetic force takes pictures of the inside of our body.
Magnet Use 3
There is a magnet in the laptops we use at school. Where you plug in your charger. It is there so the charger doesn't fall out.
Magnetic Fields
A magnetic field is the magnetic effect of electric currents and magnetic materials. The magnetic field at any given point is specified by both a direction and a magnitude; as such it is a vector field.
