The magnetic effect of electric current is used in many applications, including:
-
Electromagnetic coilsThese coils are used in electrical engineering and in devices like motors, generators, transformers, and inductors. The coil shape increases the strength of the magnetic field produced by the current.
-
Contactless position sensingThe field produced by the current in one coil can induce a current in an adjacent coil.
-
ElectromagnetsThese are useful for lifting heavy loads, separating iron and steel objects, and more.
-
Medical imagingMagnetic Resonance Imaging (MRI) machines use a strong magnetic field to align protons in the body’s hydrogen atoms.
-
Can crushersA current coil can be used as a can crusher to bend and deform a can by compressing it into a flat disc.
