Magnetodynamics Problem 1 (Induced Electric Field by Circular Magnetic Field) Consider a uniform magnetic field which points into the page and is confined to a circular region with radius R. Suppose the magnitude of B increases with time, i.e. dB/dt > 0. Find the induced electric field everywhere due to the changing magnetic field.
Question C. I don' know where to start. I've looked at worked solutions to similar problems but I can't explain why each step was taken. 3. (a) Write down the integral form of Faraday's law (Maxwell's third equation) and briefly explain what is meant by each of the terms in the equation. (3 marks) (b) With reference to Faraday's law, what is meant by the terms motional emf and magnetic induction? (2 marks) (c) Consider a uniform magnetic field that...
(11%) Problem 5: A time-dependent but otherwise uniform magnetic field of magnitude Bo(t) is confined in a cylindrical region of radius 7.5 cm. Initially the magnetic field in the region is pointed out of the page and has a magnitude of 2.5 T, but it is decreasing at a rate of 3.5 G/s. Due to the changing magnetic field, an electric field will be induced in this space which causes the acceleration of charges in the region. O B.(t) o...
In figure, an uniform magnetic field B is limited in the left half of a cylinder with Radius of R, if the magnetic field increase at a rate of dB/dt, P presents any point which have radius r from the center. (1) When r ≤ R, please find the magnitude of induced electric field field of P (2) When r>R, please find the magnitude of induced electric field field of P
In the figure a uniform electric field is directed out of the page within a circular region of radius R = 3.00 cm. The magnitude of the electric field is given by E-(5.50 × 10-3 V/m·s)t, where t is in seconds.

The induced magnetic field at a radial distance r from the central axis of a circular parallel-plate capacitor is B. If the capacitor plates have a radius R, write an expression for the rate dE/dt at which the electric field between the plates is changing.
Q1 Problem 1. 20 Points Problem 1. (20 points) A positive point charge (magnitude 191) with mass m travels to the right at constant speed 7. The charge enters a region with a uniform magnetic field and undergoes uniform circular motion with radius Ri. After the charge leaves the field region, the magnitude of the field is steadily changed over time At (the direction doesn't change). After the field stops changing, a second, identical charge with the same speed is...
