The Right-Hand Curl Rule is a method used to determine the direction of the magnetic field around a current-carrying wire or a loop. It states that if you point your right thumb in the direction of the current, then the curling fingers will indicate the direction of the magnetic field.
Imagine you are holding a screwdriver with your right hand and trying to tighten a screw. As you turn the screw clockwise, your fingers naturally curl in that same direction. Similarly, when using the Right-Hand Curl Rule, as you imagine current flowing through a wire, your fingers curl in the direction of the magnetic field lines.
Magnetic Field: A region around a magnet or current-carrying wire where magnetic forces can be detected.
Ampere's Law: A mathematical equation that relates magnetic fields to electric currents.
Solenoid: A long coil of wire often used to generate strong and uniform magnetic fields.
