… The formula for calculating the magnitude of the magnetic field is B = μ0 * (I / 2πr), where B is the magnetic field in tesla (T), μ0 is the permeability of free space (4π * 10^-7 T * m/A), I is the current in amperes (A), and r is the distance from the current-carrying wire in meters (m).
The unit of measurement for the magnitude of the magnetic field is tesla (T). Another commonly used unit is gauss (G), with 1 T = 10,000 G.
The magnitude of the magnetic field is directly proportional to the current and inversely proportional to the distance from the current-carrying wire. This means that an increase in current will result in an increase in the magnetic field, while an increase in distance will result in a decrease in the magnetic field.
The magnitude of the magnetic field refers to the strength or intensity of the magnetic field, while the direction of the magnetic field refers to the orientation of the field lines. Both the magnitude and direction are important in determining the overall effect of the magnetic field on a charged particle.
The magnitude of the magnetic field can be measured using a device called a magnetometer, which utilizes the principles of electromagnetic induction to detect and measure the strength of the magnetic field. Other methods include using a Hall probe or a ballistic galvanometer.
