Question

Which of the following statements regarding magnetic monopoles is correct?

विकल्प

• Magnetic monopoles exist only inside current loops

• Magnetic monopoles do not exist — no isolated North or South pole has ever been found

• Magnetic monopoles exist and can be isolated by cutting a bar magnet in half

• Magnetic monopoles exist only at extremely low temperatures

Answer 1

While electric dipoles are made up of monopoles (isolated positive and negative charges), magnetic monopoles do not exist — no isolated North or South pole has ever been found. The simplest magnetic element is the dipole.
