How to Find the magnetic field and the direction
Answers
Explanation:
Magnetic fields exert forces on charged particles in motion.
The direction of the magnetic force
F
is perpendicular to the plane formed by
v
and
B
as determined by the right hand rule.
The SI unit for magnitude of the magnetic field strength is called the tesla (T), which is equivalent to one Newton per ampere-meter. Sometimes the smaller unit gauss (10-4 T) is used instead.
When the expression for the magnetic force is combined with that for the electric force, the combined expression is known as the Lorentz force.
Key Terms
Coulomb force: the electrostatic force between two charges, as described by Coulomb’s law
magnetic field: A condition in the space around a magnet or electric current in which there is a detectable magnetic force, and where two magnetic poles are present.
tesla: In the International System of Units, the derived unit of magnetic flux density or magnetic inductivity. Symbol
Right hand thumb rule provides the magnetic field and its direction . imagine that you have cathed a wire in such a way that your thumb of your. right hand in the direction of current then fingers will give the direction of current . right check it dear .
