Explanation:
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. It behaves exactly like a permanent magnet, like those magnets commonly used to stick items to our fridge.
To make a permanent magnet we need:
- One iron nail ( Could be fifteen centimeters (6 in) long
)
- Three meters (10 ft) of copper wire
- One or more D-cell batteries
To make the electromagnet, we need to:
1. Wrap the Wire Around the Nail
2. Connect the Battery
And you are all set!
Your eyes and brain would first register the event nearby sooner than the one farther away
