What else can I help you with?
Why is a crane in a steelworks fitted with a large electromagnet?
Because they can then lift the steel easily without having to put chains and lifting gear onto it.
What are two ends of electromagnet called?
The two ends of an electromagnet are called the north pole and the south pole. These ends are where the magnetic field lines originate and terminate, respectively.
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 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 can happen when you put a natural magnet near an electromagnet?
When you put a natural magnet near an electromagnet, the two magnets can either attract or repel each other, depending on their polarity. This interaction can cause the natural magnet to move or align itself with the electromagnet, demonstrating the magnetic forces at play.
What are the advantages and disadvantage's of an electromagnet?
an electromagnet requires electricity and you will have to pay for it. permanent magnets are always on and you can change the strength of it.

What are the advantages of using a electromagnet at an rubbish dump?
It helps to separate metals from other rubbish such as paper and plastic.
What advantages are there in being to turn a electromagnet on and of?
Being able to turn electromagnetic on and off is what separates it from a normal magnet.

What are two advantages of a natural magnet over electromagnet?
One advantage of a natural magnet is that it does not require any external power source to maintain its magnetic properties, unlike an electromagnet that requires electricity to operate. Natural magnets are typically more stable and retain their magnetism for a longer period of time compared to electromagnets that can lose their magnetic properties when the electric current is removed.
Where are the two types of electromagnet and a bar magnet commonly used?
I'm not sure where a bar magnet is used, but an electromagnet is used in junkyards, and in some laboratories.
What is the difference in a common bar magnet and an electromagnet?
The comon bar magnet has two poles, and the electromagnet can be turned on and off also the electromagnet uses electricity to create a magnetic field in the first place. so the difference is normal magnet cant be turned on and off but the electromagnet can. does that answer ur question?
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 do the parts of an electromagnet do?
An electromagnet requires only two parts, a core of ferro-magnetic material and wires winding around it. The wires magnetize the core when current flows through them, and the core then creates the magnetic field which the electromagnet is intended to produce.
Does an electric motor have an electromagnet?
Yes. Usually two - called rotor and stator.
