An emf is induced in response to a change in magnetic field inside a loop of wire. Which of the following changes would increase the magnitude of the induced emf? A. reducing the diameter of the loop B. reducing the resistance of the wire of which the loop is made C. turning the plane of the loop to be parallel to the magnetic field D. changing the magnetic field more rapidly

which way is the induced emf (or induced current) in the
question below?
A uniform magnetic field points directly into your paper (make a sketch). A 7 turn coil of wire with a radius of 14.2 cm lies in the plane of the paper. Over a period of 0.00035 seconds, the field is increased from 0.300 T to 1.10 T. How much emf is induced in the coil while B is changing?

Moving charges will produce a local magnetic field, but the reverse is also true a changing magnetic field will similarly induce charges to move (ie. produce current). Consider a magnet moving into a coil of wire: A spinal coil of wire with many closely-spaced tums this is called a solenoid is connected to a micro-ammeter as shown in the diagram above. As the magnet moves into the coil, any induced current will be measured by the micro-ammeter. Question On the...

(Figure 1) shows an increasing magnetic field and the electric
field that accompanies it according to Faraday's law. The magnetic
field is increasing at an increasing rate.
Does the behavior of the electric field produce an additional
magnetic field?

Question7 1 pts Which statement is correct regarding Faraday's Law? O An emf is induced around a closed loop if there is a electric flux through the loop changes. The magnitude of the emf is proportional to the rate the electric flux changes with time. An emf is induced around a closed lool if the magnetic flux through the loop changes with position. The magnitude of the emf is proportional to the rate the magnetic flux changes with position O...

Problem 5. (4 points) Electric field induced by a changing magnetic field in a solenoid. long solenoid of radius R = 10 cm has n = 100 turns/cm and carries a time-varying current that varies sinusoidally as I- Imax cos (2rft), where Imax- 10 A is the maximum current and f-60 Hz is the frequency of the alternating current source. What is the maximum magnitude of the induced electric field inside the solenoid, a distance r- 1.3 cm from its...
