An electromagnetic wave is traveling in the positive x direction with its electric field along the z axis and its magnetic field along the y axis. The fields are related by: ∂B/∂x = μ0ε0∂E/∂t ∂B/∂x = –μ0ε0∂E/∂t ∂E/∂x = μ0ε0∂B/∂t ∂B/∂x = μ0ε0∂E/∂x ∂E/∂x = μ0ε0∂B/∂x An electromagnetic wave is traveling in the positive x direction with its electric field along the z axis and its magnetic field along the y axis.

At time t_1 an electron is sent along the positive direction of an x axis, through both an electric field E and a magnetic field B, with E directed parallel to the y axis. The figure gives the y component F_net, y of the net force on the electron due to the two fields, as a function of the electron's speed v at time t_1. The scale of the velocity axis is set by v_s = 95 m/s. The x...

A uniform magnetic field of magnitude 0.150 T is directed along the positive x-axis. An electron moving at 10.00 x 106 m/s enters the field along a direction that makes an angle of 60.0o with the x-axis. The motion of the particle is expected to be a helix. Calculate (a) the pitch p and (b) the radius r of the trajectory.

An electron is traveling in the positive x direction. A uniform electric field is present and oriented in the negative z direction. If a uniform magnetic field with the appropriate magnitude and direction is simultaneously generated in the region of interest, the net force on the electron can be made to have a magnitude of zero. What must the direction of the magnetic field be?
