WebThe magnetic force on a current-carrying wire in a magnetic field is given by F → = I l → × B →. 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 angle θ is 90 degrees, which means sin θ = 1. WebSal does an example problem to determine the size and direction of the magnetic force on a proton moving through a magnetic field. Created by Sal Khan. Sort by: Top Voted. ... As long as it's in the magnetic field, the force applied to the particle by the magnetic field is going to be perpendicular to the velocity of the particle. So the ... girls full zip fleece
