An electron flew into a magnetic field at a speed of 40000 km / s. The electron flies in at an angle of 30 degrees to the lines of magnetic induction, the force from the side of the magnetic field is 1.8 N. Determine the magnetic induction.
Let’s use the following formula to solve the problem:
F = q * V * B * sin l;
We know the following values for the formula:
q = 1.6 * 10 ^ -19 C;
V = 4 * 10 ^ 7 m / s;
You need to find the magnetic induction. Let’s use the formula:
B = F / (q * V * sin l);
B = (1.8) / (1.6 * 10 ^ -19) * (4 * 10 ^ 7 * 0.5);
B = 0.5625 * 10 ^ 12 T.
Answer: B = 0.5625 * 10 ^ 12 T.
