When the angle is zero degrees then both B and V are on the same plane and sin 0=0 leading to no magnetic force. So, when the charge is moving with a velocity V parallel to the magnetic field B, it will not be under the effect of a magnetic force F=0. For a magnetic force ...
The magnetic force is the force on an object due to interactions with a magnetic field. The SI unit for magnetic force is the newton (N) and the SI unit for magnetic field is the tesla (T). Anyone who has held two permanent magnets near each other has noticed the presence of a magne...
Maxwell's Fourth Equation expresses the observation that a continuous electrical current I or a displacement current (∂D/∂t) gives rise to a magnetic field. At a distance r from a wire with direct current I, for example, the magnetic field is given by (4.20G)H=2Icr (4.20S)H=I2...
The Bio-Savart law is an expression that is used to find the magnetic field strength and direction at any point in space. It is a multivariable vector integral that can be simplified into a simple algebraic expression for an infinite, current-carrying wire. What is Biot-Savart law derivation...
Lorentz force - the force experienced by a point charge moving along a wire that is in a magnetic field; the force is at right angles to both the current and the magnetic field; "the Lorentz force can be used to suspend a current-carrying object between two magnets" force - (physics) ...
If one considers the motion of electron in the presence of inner magnetic field and resistance force, a new formula for the conductivity is to be found; this formula states that the material under investigation becomes a superconductor at critical temperature and depends on the strength of the ...
Ampere’s law states that magnetic fields are related to the electric current produced in them. Know what is Ampere's law based on the magnetic field due to current along with ampere's circuital law at BYJU'S.
Consider a straight wire that carries a steady current I. Experiments (in the 19th Century) revealed that the current flow generates a magnetic field that is perpendicular to the direction of the wire and that the lines of magnetic force are circular, with the line integral ∮B·dr around a...
turns of the wire loop as μ = nia the magnetic field lines of a current loop look similar to that of an idealized electric dipole: if you have ever broken a magnet into two parts, you would have found that each piece forms a new magnet. the new pieces also contain a north and a ...
