Health and Safety
Which are the best magnets kids can use?
Parents, teachers or guardians must watch over kids, they must always be supervised when they play or experiment with magnets. Neodymium magnets are really strong so caution is required. If you suspect your child has swallowed a magnet it is important to seek the attention of a doctor immediately.
Can a magnet adversely affect my smartphone?
Are people using a pacemaker safe using magnets?
How about my wrist watch?
If your watch contains any iron or various metal materials small mechanical parts can be magnetized when you place your watch too close to a neodymium Magnet. When the mechanical parts are magnetized they can attract to each other making the watch run slow, fast or to stop completely.
Many watches today are made of materials that are ‘non-magnetic’ and are therefore resistant to weak magnetic fields. If you wear a watch it is always advised to be especially careful and keep away from strong magnetic fields.
What does a magnetic pole mean?
How are the poles identified?
Are they really ‘rare’ if they are called ‘rare earth magnets’?
Despite their name, rare earth elements are not rare, but relatively abundant on the Earth. The reason they are called ‘rare Earth’ is that they are generally not found in economically exploitable deposits, but are often dispersed.
Which of the poles are most commonly used?
What is the best way I can see a magnetic field?
What is the meaning of the “N” rating e.g. N45
There are various types of neodymium available commercially from N35 to N55, along with other variations of high temperature. For example, a neodymium magnet N35 has a product maximum energy of 35 Mega Gauss Oersted (MGOe) and N55 will have a maximum energy product of 55 Mega Gauss Oersted.
Is it safe to use adhesives to fix magnets?
Is it possible to cut a magnet?
How are magnets made?
How do these magnets work?
Is it possible to block/shield magnetic fields?
What are the differences between anisotropic and isotropic magnet
I want to stack my magnets - does it make them stronger?
How possible is it to increase the strength of my magnet?
How durable are neodymium magnets?
Which of the magnetic points have the strongest pull?
What are the factors that reduce the performance of my magnets?
The following factors are responsible for the reduction of the power of a magnet
- Steel thickness
- Air gap
- Brute force
