What else can I help you with?
How is an electromagnet different a bar magnet?
a electromagnet is bigger than a bar magnet
What represents different forms of electromagnetic radiation?
different forms of electromagnet
How is the role of an electromagnet in a motor different from the role of an electromagnet in an generator?
I thinkit is different because a motor changes eletricalenergryinto motion a generator changesa motion into eletericalenergy.
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.
What is different about an electromagnet compared to a regular magnet?
An electromagnet is different from a regular magnet because it can be turned on and off by controlling the flow of electricity through it, while a regular magnet is always magnetic.
How an electromagnet is useful in a different ways?
All electric motors are electromagnets.
Why is an electromagnet a resistor?
An electromagnet is not a resistor; they are two different components in an electrical circuit. An electromagnet uses electric current to create a magnetic field, while a resistor resists the flow of electric current, which causes a voltage drop across it.
What else could David do to an electromagnet to change its strenght?
David could change the number of wire coils wrapped around the core of the electromagnet, increase the amount of current running through the wire, or use a different material for the core to alter the strength of the electromagnet.
How do make an electromagnet stop working?
To make an electromagnet stop working, you can disconnect the power source supplying electricity to the electromagnet. This will interrupt the flow of current through the coil of wire, which is necessary to generate the magnetic field. Alternatively, you can reverse the direction of the current flow by connecting the wires in a different way, which will cancel out the magnetic field.
Is a refrigerator magnet electromagnetic?
IT is different because an electromagnet runs with electricity. A refrigiator does not run with electricity.
How is electromagnet different from a regular bar or horseshoe magnet?
It requires a current through a coil of wires.
Which is better a permanent magnet or an electromagnet?
electromagnet
