An infinite straight wire refers to an idealized wire with no end that carries an electric current.
congrats on reading the definition of Infinite Straight Wire. now let's actually learn it.
Biot-Savart Law: A fundamental law in electromagnetism that calculates the magnetic field produced by a current-carrying wire.
Right-hand Rule (for wires): A rule used to determine the direction of magnetic fields generated by current-carrying wires.
Solenoid: A coil of wire wound in a helical shape that produces a uniform magnetic field when carrying an electric current.
