1. Magnetism from Electric Currents
Chapter 18 Section 2
Physical Science

2. Electromagnetism
When electricity passes through a metal wire it creates a strong electric current and a magnetic field.
This device is known as an solenoid.
A nearby compass will react to the magnetic field.

3. Electromagnetism
If a solenoid is wrapped around a magnetic metal (e.g., iron, cobalt, or nickel) it will create an electromagnet.

4. Electromagnetic Devices
An electric motor can convert electrical energy into mechanical energy.

5. Electromagnetic Devices
A galvanometer is used to measure current (amperage/A).
