1. Physical Science Mr. Barry

2.  Properties of Magnets:  Magnets have magnetic fields, which exert forces on other magnetic materials  Magnets have a north pole and a south pole

3.  Magnetic field lines travel from the magnet’s north pole to the south pole  Magnetic fields are strongest at the magnet’s poles

4.  Electrons have magnetic properties. In some materials, the electrons exert magnetic forces on nearby electrons, and groups of particles align their magnetic fields. These groups are called domains.

5.  If another magnetic field exerts a force on the domains, the domains will line up, creating a magnet. This is how a paperclip can become temporarily magnetized when placed in a magnetic field

6.  An electric current traveling through a wire produces a magnetic field around the wire  An electric current traveling through a coil of wire produces a magnetic field inside the coil. This creates an electromagnet
