Which material do we use in the core of an electromagnet and why?
Soft iron is used as the core of an electromagnet. It increases the strength of the magnet.
What suitable material would you use for the core of an electromagnet?
Iron - use a bunch of iron nails, wrapped many times with insulated copper wire, if making your own electromagnet.
Can zinc be used in an electromagnet?
no...only magnetic materials can be used as electromagnet...zinc is not a magnetic material
An electromagnet is a solenoid with a piece of ferromagnetic material within it?
True
Is An electromagnet is a solenoid with a piece of ferromagnetic material within it?
True
When making an electromagnet should you use an iron or aluminum nail?
Aluminium is not a magnetic metal.
Can you use an aluminum core for the magnet?
I cannot remember for sure, but in an electromagnet, an aluminum core would not have any permeability to add to the electromagnet's strength. An electromagnet is more efficient when a thicker core is used; it generates more power. The material you use should be prone to magnetism, as in attracted by permanent magnetic apparatuses or the such. So, an aluminum bar/core (cannot be magnetized), like you stated, wouldn't be the best choice for your magnet's core.
What is one example of use of an electromagnet?
EXAMPLES OF AN ELECTROMAGNET ARE CARS, GENARATORS
How do you use a electromagnet?
electromagnetically
You can increase the strength of an electromagnet field by?
using a stronger ferromagnetic material for the core. :)
Does a doorbell use an electromagnet?
yes it does
Does an electric lamp use an electromagnet?
No.
