A square loop of side 25.0 cm is inserted into a magnetic field directed into the page. Initially, the magnetic field has a magnitude of 0.950 T. The rate of decrease of the magnetic field is -0.0650 T/s. Consider an insulator in the loop separating two ends of the loop from touching. Calculate the emf induced in between the ends.

Consider a uniform magnetic field that is perpendicular to the plane of the area of a circular coil having a radius of 5 cm, moving with a speed of 5 m/s. Determine the induced emf in the coil if the speed and magnetic field are both doubled.

Current is increasing uniformly at a rate of 38.0 A/s through a solenoid with a radius of 3.0 cm and has 800 turns per meter. Calculate the electric field induced, measured near the midpoint of the solenoid at a radial distance of i) 0.75 cm and ii) 1.25 cm from the solenoid's axis.

A team of scientists designed and created a conducting polymer-based wire that is super stretchable and has high conductivity. The wire is stretched into a circular loop of circumference 2 m. The wire is placed with its plane perpendicular to a uniform 0.200 T magnetic field. When released, the circumference of the loop starts to shrink at a uniform rate of 15.0 cm/s. Determine the induced emf in the loop after exactly 11s.

A cylindrical solenoid measures 16 cm in length and 5.0 cm in diameter and is wound with 200 turns. The figure below shows the current as it changes over time for this solenoid. Using this information, determine and graphically represent the magnitude of the induced electric field at a point 2.0 cm from the solenoid's central axis, as a function of time.

An ignition system is comprised of two tightly-wrapped coils of wire, each with a radius of 0.50 mm, around a soft iron core measuring 1.5 cm in radius. The primary coil, with 200 turns, is located closer to the iron core. The secondary coil, with 20,000 turns and a 0.50-ohm wire, is wrapped around the primary coil as shown below.When the ignition switch is turned on, the current in the primary coil is shown in the graph. Assume the magnetic field generated by the primary coil passes entirely through the secondary coil. Determine the maximum induced current in the secondary coil at (i) t = 0.5 ms and (ii) t = 1.5 ms. A positive current is clockwise of the coil.

A circular loop of diameter 40.0 cm is inserted into a magnetic field directed into the page. Initially, the magnetic field has a magnitude of 0.850 T. The rate of decrease of the magnetic field is -0.0400 T/s. Determine the value of induced emf between the points p and q on the loop. Use shortest length between p and q.
