The 11 pages that link to Electromagnet, each with the reason it gives.

• RelayBroader topic: In an electromechanical relay, its magnetic field pulls the armature toward the coil.

• MagnetostaticsBroader topic: Its field is designed using magnetostatic laws when the current is steady.

• Neodymium magnetCompared with: Unlike a neodymium magnet, an electromagnet’s field can be switched or varied electrically.

• Permanent magnetCompared with: Unlike a permanent magnet, its field can be controlled by changing the current.

• Samuel MorseRelated: Electromagnetic action let telegraph circuits operate recording and signaling devices.

• Joseph HenryRelated: Henry built powerful electromagnets and used them to investigate electrical and magnetic effects.

• Rare-earth magnetCompared with: Unlike rare-earth permanent magnets, it can be switched or adjusted electrically.

• Magnetic circuitRelated: Its field strength can be estimated from coil magnetomotive force and core reluctance.

• Right-hand ruleBroader topic: The rule helps determine its polarity from the winding and current direction.

• Pavel SchillingRelated: Electromagnetic effects enabled Schilling’s apparatus to move its receiving needles.

• Methods in magnetismRelated: Laboratory measurements use electromagnets to set and vary applied fields.
