Hola, tengo el siguiente problema y me gustaría que me echárais una mano para su resolución:
A Hall-effect probe operates with a 120-mA current. When the probe is placed in a uniform magnetic field of magnitude 0.080 T, it produces a Hall voltage of 0.700 microV.
a) When it is measuring an unknown magnetic field, the Hall volage is 0.330 microV. What is the magnitude of the unknown field?
b) The thickness of the probe in the direction of B is 2.00 mm. Find the density of the charge carriers, each of which has charge of magnitude e (electron).
Que alguien me dé alguna pista de cómo resolverlo por favor...
Saludos
