Explain how does an MRI machines works
MRI scanners use powerful magnets and RF pulses to excite hydrogen protons in water molecules within the body. The emitted signals are then used to construct images, which can show clear differences between healthy and diseased tissue
What is an electromagnet?
An electromagnet is a type of magnet where the magnetic field is generated by an electric current. It typically consists of a coil of wire wound into a coil, often around a soft metal core like iron, which enhances the magnetic field produced by the wire.
