What must happen for an electromagnet to have a magnetic field?
An electromagnet must have a current flowing through its coil of wire in order to generate a magnetic field. When an electric current passes through the coil, it creates a magnetic field around the electromagnet.
What must pass through a coil in order to make an electromagnet?
An electrical current will cause an electromagnet to energise.
What must happen for an electromagnet to have a magnetc field?
An electromagnet must have an electric current passing through its coils to generate a magnetic field. The magnetic field is created as the electric current causes the alignment of the magnetic domains within the core material of the electromagnet, creating a magnetic field around the coil.
Do you have to connect a cell to work an electromagnet?
A cell or other (DC) power source must, indeed, be connected to an electromagnet to make it work. It is an electromagnet. Surf the link to our friends at Wikipedia. It's a good article, and the pics are cool.
What must flow through the coil of wire to make the electromagnet work?
An electric current must flow through the coil of wire to make the electromagnet work. This current creates a magnetic field around the coil, inducing magnetism.
What must you have for an electromagnet to work that you don't need for a regular magnet?
To make an electromagnet work, you need an electric current flowing through a coil of wire, which is not needed for a regular magnet.
How can a electromagnet pick up more metal things?
More than what? - An electromagnet can pick up metal due to its magnetism - assuming it is turned on. If you increase the current, the electromagnet becomes more powerful - but you must be careful not to pass too much current, otherwise the wires might burn through.
Which is better a permanent magnet or an electromagnet?
electromagnet
An electromagnet becomes storgner when the?
an electromagnet becomes storgner when the.
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.
Which two minerals must be included on the nutrition facts label?
Calcium and iron must be included on the Nutrition Facts label.
What is a magnet made by electric current?
An electromagnet.
