Magnets are atomic powered. The difference between a permanent magnet and a temporary magnet is in their atomic structures. Permanent magnets have their atoms aligned all the time. Temporary magnets have their atoms aligned only while under the influence of a strong external magnetic field. Overheating a permanent magnet will rearrange its atomic structure and turn it into a temporary magnet. Materials with magnetic properties posses magnetic fields.

An electromagnet is a kind of magnet whose magnetic field is created by the flow of electric current. The magnetic field disappears when the current stops. Electromagnets offer the advantages of controlled holding power and on command release. Through the application of controlled DC electrical current, electromagnets have the ability to attract and hold ferrous materials with varying degrees of force, and to release the item as required. Adams supplies electromagnets in a variety of sizes, shapes and current strengths to meet your end-use requirements.

Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. It only takes a minute to sign up. It will be helpful if you try to explain it without going into special relativity, or higher level calculus. Electricity and Magnetism are the two sides of the same coin. Magnetism is produced only due to the effect of moving charges, every charged body in motion acts like a magnet.

Difference between Permanent Magnet and Electromagnet is magnetic field and strength. In Electromagnet, the magnetic field is created by a wire-wound coil but the magnetic field of Permanent Bar Magnet cannot be changed. The strength of Permanent Magnet depends on the material used for its creation, on the other hand, the strength of Electromagnet varies according to the flow of electric current into it. Each has its own applications and types. These types of magnets can retain their magnetism and magnetic properties for a longer time.

Write the differences between a bar magnet and an electromagnet.


Comparison of Electromagnet and permanent magnet

In an electromagnet the magnetic field is created through electric current in a wire-wound coil and strengthened by a soft-iron core. A permanent magnet is made of ferromagnetic material, which is magnetised by a strong external magnetic field. The magnetically hard material that.
