When anelectric currentpasses through a wire, it creates a magnetic field around it. Also, thismagnetic fieldforms concentric circles around the wire. Furthermore, the direction of the magnetic field depends upon the direction of the current. Moreover, we can determine it by using the ‘right-...
Once electric current passes through a wire, loop, or solenoid a magnetic field is generated and can be found in the surrounding area by using a compass. The compass needle will point in the direction of the magnetic field.Magnetic Force Formula The magnetic force formula is written as F→=...
which was recently derived for the circulation of the magnetic field created by a finite portion of wire carrying a slowly varying current, is used with the superposition principle and symmetry considerations to obtain an expression for the magnetic field of a thin cylindrical...
Additionally, electric field is a vector quantity, while magnetic field is a vector field.How do you calculate the magnetic field of a current-carrying wire? The formula for calculating the magnetic field of a current-carrying wire is B = μ0I/2πr, where B is the magnetic field, μ0 ...
History of Magnetic Field The research on the magnetic field began in 1269 when French scholar Petrus Peregrinus de Maricourt mapped out the magnetic field on the surface of a spherical magnet using iron needles. He noticed that the resulting field lines crossed at two points. He named these ...
A magnetic field is avector, which means it has magnitude and direction. Ifelectric currentflows in a straight line, the right hand rule shows the direction invisible magnetic field lines flow around a wire. If you imagine gripping the wire with your right hand with your thumb pointing in th...
Outside of a solenoid, the magnetic field is exactly 0. How do I calculate the magnetic field inside a solenoid? To calculate the magnetic field inside a solenoid: Measure the current in the wire, I; Count the number of complete coilings in the solenoid, N; Measure the length of the ...
