In this form it is written using the vector cross product.

Formula of magnetic force in physics. It is the combined electric and magnetic force on. F I d l. 10112020 Magnetic Force Equation Suppose a charge q is moving with a velocity v in a magnetic field of strength B the formula for the magnetic force is F qv X B F q v X B Here F is represented as a vector and v x B is the cross product of v and B.

This implies that the magnetic force on a stationary charge or a charge moving parallel to the magnetic field is zero. Written in terms of the angle between the velocity vector and the magnetic field vector. Of the wire specifies the direction in which the current is flowing.

Magnetic materials can have a wide variety of properties and the shape of the object also has a significant effect on the fields in and around it and so on the forces. 13012021 The magnetic force on a current-carrying wire in a magnetic field is given by F Il. We can write the magnitude of the magnetic force by expanding the cross product.

This is again analogous to the electrostatic case but with added complication due to current being a vector. B where q is the charge B is the magnetic field and v is the velocity of the charge. 20052005 Well magnetic force is defined as F b q v.

The formula for the force depends on the charge of the particle and the cross product of the particles velocity and the magnetic field. - If a bar-shaped permanent magnet is free to rotate one end points north north pole of magnet. The angle θ is 90 degrees which means sinθ 1.

Exert forces on each other as well as on unmagnetized Fe pieces. F qEr v times Br This above force is termed as the Lorentz Force. Mathematically we can write magnetic force as.

The value of the magnetic force depends on how much charge is in the motion. - The needle of a compass is a piece of magnetized Fe. The direction of the force.

From this point of view the magnetic force F on the second particle is proportional to its charge q 2 the magnitude of its velocity v 2 the magnitude of the magnetic field B 1 produced by the first moving charge and the sine of the angle theta θ between the path of the second particle and the direction of the magnetic field. Magnetic Force Formula Charge-Velocity When a charged particle moves in a magnetic field a force is exerted on the moving charged particle. Magnetic Force Formula Current-Length When a wire carrying electric charge is placed in a magnetic field a force is exerted on the wire.

For part a since the current and magnetic field are perpendicular in this problem we can simplify the formula to give us the magnitude and find the direction through the RHR-1. The force is zero if the second charge is travelling in the direction of the magnetic field. The magnitude of the force is F qvB sinθ where θ is the angle 180 degrees between the velocity and the magnetic field.
