Magnetism and electricity can be considered as a two side of the same coin. The two are closely related and this relation was discovered by the Danish physicist Hans Christian Ørsted. Michael Faraday built upon Hans’ discovery and eventually led to significant contributions in the field of electromagnetism, such as diamagnetism and electromagnetic induction.
Today, the concept of electromagnetism finds applications in many fields, but the most notable is in the field of medicine – The MRI (Magnetic Resonance Imaging).

What is meant by ‘Magnetism’?
The characteristics of a magnet to attract or pull other magnets/magnetic objects is known as ‘Magnetism’.
What is the benefit of having a magnetic field?
A major benefit of having a magnetic field is its use of navigation. The Earth is a place of habitation because of its magnetic fields.
Can wearing magnets or magnetic objects cause harm?
Although they have been used in various diagnostic devices in the health sector and as therapeutic tools, magnets are potentially harmful to the body and pose increased risk of accident.
