What happens when you decrease the current in an electromagnet?
When you decrease the current in an electromagnet, the magnetic field decreases.
How do you make a railway signal using electromagnet?
how to make road rail signal using electromagnet
Does using thicker wire make a electromagnet more powerful?
The wire in a electromagnet is the conductive property transferring power. The thicker the wire the more power transferred to the electromagnet for a exponential amount of power.
How does the number of wraps of wire affect the strength of an electromagnet?
The more turns of wire in an electromagnet the stronger the magnetic field.
Does an electric lamp use an electromagnet?
No.
Why are there more thumbtacks attached in electromagnet b as compared to electromagnet a?
I'm having a lot of trouble seeing the picture that goes along with this question in the book, so I'll have to take a wild guess based on no information. My guess is that electromagnet 'b' has more current flowing in its wire coil than electromagnet 'a' has. Another possibility is that the current through both coils is the same, but the coil of electromagnet 'b' is wound with more turns of wire than the coil of electromagnet 'a' is. It's just a guess. To be sure, I really need to see that picture.
Which is better a permanent magnet or an electromagnet?
electromagnet

What does an electromagnet operator do to release metal attached to the electromagnet?
An electromagnet operator can release metal attached to the electromagnet by turning off the electric current flowing through the electromagnet coils. This de-energizes the electromagnet, causing the magnetic field to dissipate and the metal object to fall off.
What is a magnet made by electric current?
An electromagnet.

Why electromagnet is different from a permanent magnet because an electromagnet what?
Mainly in that the electromagnet is NOT permanent. In other words, it can be switched on and off.Another relevant difference is that the electromagnet constantly requires power, at least while it is on.
Who built the first electromagnet?
Linc Robinson built the first electromagnet.
When was the electromagnet invented?
The electromagnet was invented in the year 1850 by william sturgeon :)
What is the difference between electromagnetism and electromagnet?
electromagnetism is the force an electromagnet is the object
An advantage of an electromagnet (in contrast to a bar magnet) is?
An electromagnet can be turned on and off.
