The direction of the magnetic force →F is perpendicular to the plane formed by →v and →B as determined by the right-hand rule-1 (or RHR-1), ...
Magnetic field
https://en.wikipedia.org
A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. ... A permanent magnet's magnetic field pulls ...
Magnetic Fields
https://isaacphysics.org
In electric fields we take the field's direction to be the direction of the force on a positive charge. Similarly, the direction of the magnetic flux density is ...
Magnetic Fields and Magnetic Field Lines
https://courses.lumenlearning.
The direction of the magnetic field is tangent to the field line at any point in space. · The strength of the field is proportional to the closeness of the lines ...
Using the Right
https://www.khanacademy.org
The magnetic field made by a current in a straight wire curls around the wire in a ring. You can find it by pointing your right thumb in the direction of the ...
What is the direction of magnetic field lines?
https://physics.stackexchange.
Magnetic field lines are closed loops. Inside the magnet they run from South Pole to North; outside they run from North Pole to South.
What is the direction of the magnetic field lines surrounding a ...
