Web$\begingroup$ Because it produces a changing magnetic field. And Maxwell's equations (Faraday's law) teach us that a changing magnetic field results in an electric field, which gives rise to a current in a nearby wire.It's not the magnetic field providing the force, it's the electric field generated by the changing magnetic field. (note that the current vanishes … WebLenz's law states that whenever there is a change in the magnetic flux through a conducting loop, a current arises to produce a magnetic field that balances the change, i.e. to keep \(\int_A \vec{B}\cdot \vec{n}\) constant. This is a result of Faraday's law of induction.. An externally applied magnetic field through an area induces a current. The induced …
WebInduced Magnetism When a magnetic material (not a magnet) enters a magnetic field it experiences induced magnetism. When it is removed from the field it is no longer magnetic. Temporary Magnetism Magnetic materials can be magnetised by: Stroking it with a magnet Leaving it near to a magnet for a long time WebBar magnets and horseshoe magnets are examples of permanent magnets.

WebA permanent magnet is called a permanent magnet because its magnetism is ‘always on’, it generates its own persistent magnetic field unlike an electromagnet which is made from a coil of wire wrapped around a steel core and requires an electric current to generate a magnetic field.
