What is the difference between a permanent and a temporary position? A permanent position is one where there is no defined employment end date and the employee receives a benefits package. A temporary position is one that has a defined duration of employment with a contract end date.
Q. What happens if a bar magnet is broken into two pieces?
When a bar magnet is broken into two pieces then each piece will have unlike poles. Since magnetic monopole does not exist so if you do the breaking process repetitively then you will end up with each piece having unlike poles.

Q. How heating a bar magnet would change its magnetic field?
When the magnet is heated, the atoms in the magnet gain kinetic energy and move faster. The atoms move so fast that they collide with other atoms, causing atoms in domains to become unaligned. This would reduce the magnetic field.
Q. What are the temporary and permanent magnet?
A permanent magnet is one that retains its magnetic properties for a long period of time. Examples are iron, nickel, cobalt and some rare earth alloys etc. Temporary magnets are those that simply act like permanent magnets when they are within a strong magnetic field.
Q. What is the difference between a temporary and a permanent magnet class 6?
Characteristics, properties & types of magnets….
| Temporary magnet | Permanent magnet |
|---|---|
| It cannot convert an ordinary piece of iron into a magnet because of its weak power. | It can convert an ordinary piece of iron into a temporary magnet. |
| It is made of soft (pure) iron. | It is made of steel, cobalt and nickel. |
Q. How magnet lose their properties?
If a magnet is exposed to high temperatures, the delicate balance between temperature and magnetic domains is destabilized. At around 80 °C, a magnet will lose its magnetism and it will become demagnetized permanently if exposed to this temperature for a period, or if heated above their Curie temperature.
