Here are 2 concise excerpts from a book I have been reading:-
1.A permanent magnet produces its own magnetic field. An induced magnet is a material that becomes a magnet when it is placed in a magnetic field. Induced magnetism always causes a force of attraction. When removed from the magnetic field an induced magnet loses most/all of its magnetism quickly
- The force between a magnet and a magnetic material is always one of attraction.
I am trying to link the two excerpts that have been given separately. What I understand is stated below:-
- A permanent magnet produces its own magnetic field(excerpt 1)
- This permanent magnet's magnetic field can induce a magnetic material(not magnet) to become a magnet(excerpt 1)
- The poles on the induced magnet are induced opposite to the poles on the permanent magnet
- As the poles are induced opposite, the force between the magnet and former magnetic material(now induced magnet) is attractive(excerpt 2)
- As the induced magnet is taken away from the permanent magnet-it loses it magnetism and hence, is not a magnet(excerpt 1) and hence, returns to being a magnetic material.
First of all, is my understanding accurate? Secondly, does that mean the way that magnets attract magnetic materials(not magnets though) is by turning them to induced magnets?
