How is an electromagnet different from a regular bar magnet?
An magnet is a material or object that creates a magnetic field. Bar magnets constantly create their magnetic field, while electromagnets are coils that only produce a magnetic field when an electric current passes through it.
What does a electromagnet have that a bar magnet does not have?
The bar magnet and the electromagnet act identical. The difference being a electromagnet is a coil of wire that has a power source connect to both ends, this energizes the coil with an electromagnetic field.
When would an electromagnet stop working?
Oh, dude, an electromagnet would stop working when the current flowing through its coil is turned off. It's like when you unplug your phone charger, it stops charging - same concept, man. So, yeah, no current, no magnetic field, no magnetism.
What happens with the energy associated to the magnetic field of a coil with electric current if the electric current is turned off?
The magnetic field or energy associated with the magnetic field will no longer be generated if the current is turned off.
What is elecotromagnet?
An electromagnet - is essentially a metal 'core' encased in wire. When power is applied to the wire, the core becomes magnetic - when the power is turned off, the magnetism is lost. Think along the lines of a crane in a scrap-yard. The crane has an electromagnet attached to its lifting arm. The operator switches on the magnet to lift a load of scrap metal, and switches it off to drop the load.
When this is turned off the electromagnet is no longer magnetic?
Electric current.
Is electromagnet a permanent magnet?
No, an electromagnet is not a permanent magnet. It is a magnet that produces a magnetic field when an electric current is passed through it, and the magnetic field disappears when the current is turned off.
An electromagnet is a type of what?
An electromagnet is a type of magnet that becomes magnetic when an electric current flows through it and loses its magnetism when the current is turned off.
What advantage does an electromagnet have against a bar magnet?
An electromagnet can be turned on and off by controlling the electric current, giving it more versatility in applications. Additionally, the magnetic strength of an electromagnet can be easily adjusted by changing the amount of current flowing through it.
Is a electromagnet a temporary magnet yes or no?
Yes, an electromagnet is a temporary magnet. It only exhibits magnetic properties when an electric current is flowing through it, and the magnetism disappears when the current is turned off.
When is magnetism lost in an electromagnet?
Magnetism is lost in an electromagnet when the electric current flowing through the coil is turned off or interrupted. This interrupts the magnetic field generated by the coil, causing it to demagnetize.
How does an electromagnet's magnetic field differ from that of a permanent magnet, and does an electromagnet possess both a north and south pole?
An electromagnet's magnetic field can be turned on and off by controlling the electric current flowing through it, while a permanent magnet's field is always present. An electromagnet can have both a north and south pole, depending on the direction of the electric current.
What is the difference from a normal magnet to an electromagnet?
A normal magnet is a static magnet that produces a magnetic field without needing an external power source. In contrast, an electromagnet is a magnet created by passing an electric current through a coil of wire, producing a magnetic field that can be turned on and off by controlling the electric current.
Electromagnet is a temporary magnet because you can?
turn it off by unplugging the current source.
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 happend to a electromagnet when you turn it off?
When you turn off an electromagnet, the magnetic field it was producing disappears and the magnetism is lost. This is because an electromagnet relies on the flow of electric current to produce the magnetic field, and when the current is turned off, the magnetism is no longer sustained.
What does the electromagnet pick up?
An electromagnet can pick up magnetic materials such as iron, steel, nickel, and cobalt. It attracts these materials when it is magnetized by an electric current, and loses its magnetism when the current is turned off.
