A solenoid is a long coil of wire with multiple turns. When current flows through the solenoid, it creates a strong and uniform magnetic field inside. A solenoid with an iron core can act as an electromagnet, which is used in various devices.

The strength of the magnetic field inside a circular loop increases with the number of turns. More turns create a stronger magnetic field at the center of the loop.

Increasing the current increases the strength of the magnetic field around the conductor. The magnetic field strength is directly proportional to the current.

The magnetic field strength decreases as the distance from the conductor increases. The field is strongest near the conductor and becomes weaker as you move farther away.

The magnetic field lines around a straight current-carrying conductor form concentric circles around the wire. The direction of the magnetic field can be determined using the right-hand thumb rule.
