# Magnetic Field and Strongest Electromagnet

Topics: Magnetic field, Electromagnetism, Magnetism Pages: 3 (301 words) Published: August 17, 2013
Explain what it means when we say a substance is magnetic.
A substance can be picked up by a magnet. Discuss the relationship between electric and magnetic fields. The magnetic field will be perpendicular to the electric field and vice versa Before you begin your lab, you need to form a hypothesis that reflects which material, voltage, and number of winds you think will produce the strongest electromagnet. Record your hypothesis as an if then statement.

If I use copper, 100 volts, large thickness, and 100 winds, I will have the strongest electromagnet.

￼￼￼￼￼￼￼￼￼￼￼

Review your data. Did your experiment prove or disprove your hypothesis? Explain your answer. It proved my hypothesis. The copper, 100 volts, large thickness, and more winds made the strongest electromagnet..What role does voltage play in the formation or use of an electromagnet? More voltage causes more current which in return gives you a stronger magnet. If you were able to keep the electromagnet that you created in your laboratory activity, what would be two possible uses for the electromagnet? Pick up objects that have been dropped, to prevent bending over (maybe for a handicapped) and getting objects out of cabinets that are magnetic (again useful if handicapped) What is an advantage of using an electromagnet rather than a regular magnet? It is a stronger magnet and you can control it better.
