❓ why
Why do electromagnets get stronger when you add more coil turns?
Quick Answer
More turns of wire create more combined magnetic field around the core. The fields add together, making the electromagnet stronger for the same current.
The Full Story
Each loop of wire carrying current produces its own magnetic field. When many loops are wound into a coil, the fields reinforce one another along the coil’s axis, especially if an iron core is added. This is why solenoids and electromagnets become stronger with more turns and with greater current. The principle is used in cranes that lift scrap metal, relays, speakers, and electric motors.
Key Facts
1.Field strength increases with the number of coil turns
2.Iron cores concentrate and strengthen magnetic fields
3.Electromagnets are used in cranes and motors
