CLOCKWISE
According to lenz's law, E will be produced in such way that induced magnetic field decreases(as external magnetic field increases with time)
for the above situation, induced magnetic field will be in downward direction.From right hand rule, E will be in clockwise direction

A car is going with a constant tangential acceleration (i.e. increasing speed) in a circular path. As seen from above, the path is counter-clockwise. It crosses the point 'A' at time 0.00, at which point its speed is known. Find the direction of its centripetal acceleration at some time after it crosses the point A:Write your answer in degrees. Given: Speed when it crosses point 'A' - V-3.6 m/s, tangential acceleration a 3.6 m/s2, radius of path...

Learning Goal: To understand the terms in Faraday's law and to be able to identify the magnitude and direction of induced emf. Faraday's law states that induced emf is directly proportional to the time rate of change of magnetic flux. Mathematically, it can be written as E=???B?t, where E is the emf induced in a closed loop, and ??B?t is the rate of change of the magnetic flux through a surface bounded by the loop. For uniform magnetic fields the...

A) By substituting in the base units show how the units for Faraday's law reduce to be equivalent. emf(volts) = rate of change of magnetic flux (Tesla - meters^2 per second) V = Tm2/s B) A common way to induce an emf in a conductor is to rotate a coil of wire in a uniform magnetic field. If you have circular coil of radius 1.27 cm in a 2.0 T field, what is the maximum flux? a. 1.57x104 T m2...

Is there any phase difference between the electric wave and the magnetic wave? (g) The electric field you found in part (e) should also satisfy Ampére-Maxwell equation. Find the speed of the EM wave in terms of the constants en and yo using this requirement.

Induction and Faraday's Law In the long solenoid shown in the figure, the number of turns per unit length is n_1 = 220 turns/cm. At the center of this solenoid there is a shorter solenoid made of N_2 = 130 turns closely spaced. The diameter of the smaller solenoid is d_2 = 2.1cm, and its axis coincides with the axis of the longer solenoid. The current in the first solenoid grows linearly by an amount delta I = 1.5 A...
