The area vector with the field will be (90 – 90) = 0 since the plane is normal (90).

B (magnetic field) = 0.2 T

A (area) = 0.05 cm²

= 0

The formula Flux() predicts that

= B A cos

= 0.2 0.05 cos (0)

Keep in mind that cos (0) = 1.

= 0.01 Wb

An electron feels the strongest magnetic force when it enters a magnetic field perpendicular to it. The formula for this force is F = qvB, where B is the strength of the magnetic field, q is the electron’s charge, v is its velocity, and F is the magnetic force. The force is greatest at a 90-degree (perpendicular) angle between the velocity and magnetic field vectors.

Heat loss can occur when induced voltages cause eddy currents to flow through a transformer’s core. The core’s silicon steel lamination considerably lowers this heat loss.

q = 2 C

B = 4 T

v = 20 m/s

F = q (v × B)

Since q and B are parallel, there is no net force acting on the charge.

The quantity of magnetic field lines that flow through a surface is referred to as magnetic flux. The scalar product of surface area A and magnetic field B is known as magnetic flux.

ΦB = B ⋅ A = B A cos θ

Magnetic flux has no direction and only magnitude because it is a scalar quantity. Therefore, it is impossible to determine its “direction” by using any rules.

The “magnetic field, velocity, and length of the rod” are the only variables that affect “Motional emf.”
