It is important that Children are at all times supervised when playing with magnets. Neodymium magnets can be too strong for children and if swallowed the child may require immediate surgery .
The heart pacemakers may be affected by the magnet if they are in close proximity as they can cause pacemakers to operate in a way that does not adhere to the user’s own heart beat or rhythm.however, The way a pacemaker signals to a magnetic is different depending on manufacturers and therefore people with pacemakers should not put strong magnets close to their chest.
A permanent magnet is a made by solid material that produces its own consistent magnetic field , the magnetic field produces an electromagnet by the flow of electric current. The magnetic field disappears when the current is turned off.. When an electric current flows around the solenoid coil, a magnetic field is made. If
There are five types each made from different materials some are strong magnets, referred better known as neodymium magnets which are made from an alloy of neodymium, iron and boron (NdFeb) and samarium cobalt magnets which are made from samarium, cobalt and small amounts of iron, copper and other materials. Other types of permanent magnets include ferrite magnets, made from a compound of ceramic material and iron oxide (SrO.6Fe2O3) and alnico magnets made from aluminium, nickel and cobalt and flexible rubber.
A magnet’s pole is the surfaces from which rays magnetism exit a magnet and reconnect on on their way back to the magnet. The pole of a magnet is the area which has the greatest magnetic field strength in a given direction.a pole is either north or south facing.
Both the north pole or south pole of a magnet are equal in holding power and both will stick to magnetic metals.
Most magnets can be stuck in place where there is a two-part epoxy adhesives. We recommend Araldite Rapid which sets.
