Currents I1 = 1 A and I2 = 3 A pass through two conducting parallel wires placed in the same plane, as shown in the figure. a) Explain why the resultant magnetic field is zero only at point K. [3] b) If the currents are separated by a distance d = 30 cm, what is the distance between current I1 and the point K where the resultant magnetic field is zero?

Within the green dashed circle shown in the figure below, the magnetic field changes with time according to the expression B = 3.00t3 − 2.00t2 + 0.800, where B is in teslas, t is in seconds, and R = 2.40 cm. (a) When t = 2.00 s, calculate the magnitude of the force exerted on an electron located at point P1, which is at a distance r1 = 4.80 cm from the center of the circular field region. N (b) When t = 2.00 s, calculate the direction of the force exerted on an electron located at point P1, which is at a distance r1 = 4.80 cm from the center of the circular field region. tangent to the electric field line passing through point P1 and clockwise tangent to the electric field line passing through point P1 and counterclockwise The magnitude is zero. (c) At what instant is this force equal to zero? (Consider the time after t = 0 s.) s
