A solenoid is a type of electromagnet formed by a helical co | Physics
A solenoid is a type of electromagnet formed by a helical coil of wire whose length is substantially greater than its diameter, which generates a controlled magnetic field. The coil can produce a uniform magnetic field in a volume of space when an electric current is passed through it. The term solenoid was coined in 1823 by André-Marie Ampère. ━━━━━━━━━━━ @Physics | @Education
