What makes electromagnetic radiation so useful?

• antenna/bandwidth

• Electrons

• conservation of energy

• travels through space in waves, doesn't rely on wires, travels at high speeds

One type of energy can be converted into another. Electrical energy is converted into mechanical energy when a fan is plugged into a power source and turned on.

• antenna/bandwidth

• Electrons

• conservation of energy

• travels through space in waves, doesn't rely on wires, travels at high speeds

Electricity is made up of ____________traveling through wires that are connected to a power source

• antenna/bandwidth

• Electrons

• conservation of energy

• travels through space in waves, doesn't rely on wires, travels at high speeds

In a server farm a more powerful________________could increase the ________________________ to allow more users to connect quickly at any given time

Using wire, a nail, and a battery to create three different electromagnets of varying strength. How can the same materials be used to create a stronger electromagnet?

• antenna/bandwidth

• Electrons

• conservation of energy

• Add more loops of wire around the nail to increase the magnetic field.

Kira is creating a list of the possible ways that the strength of an electromagnet can be altered. What is one thing that WON'T work?

• antenna/bandwidth

• Electrons

• adding an insulator to the electromagnet

• Add more loops of wire around the nail to increase the magnetic field.
