!The strength of a magnetic field is directly proportional to the amount of current flowing through a conductor. This means that as the current increases, the magnetic field strength also increases.
The magnetic field strength is measured using a unit called Tesla (T). Other common units include gauss (G) and microtesla (µT).
The magnetic field strength is affected by the amount of current, the distance from the source of the current, and the material through which the current is flowing. Additionally, the shape and orientation of the conductor can also impact the magnetic field strength.
Magnetic field strength refers to the strength of the magnetic field at a specific point in space, while magnetic flux density is a measure of the number of magnetic field lines passing through a given area. In other words, magnetic field strength is a vector quantity, while magnetic flux density is a scalar quantity.
The direction of current flow determines the direction of the magnetic field. In a straight conductor, the magnetic field lines form concentric circles around the conductor, with the direction of the field being determined by the right-hand rule.
