Homework Answers
Induced magnetic field opposes the change in flux. ( First option)
Reason - as long as there is no change in magnetic field or area over which field is applied , no change in flux will take place, so no induced magnetic field will occur
Therefore,
we can say Induced magnetic field ONLY occurs to oppose change in flux, if any.

To practice Tactics Box 25.1
Using Lenz's law. Lenz's law is a useful rule for determining the
direction of the induced current in a loop. Specifically, it says
that there is an induced current in a closed conducting loop if and
only if the magnetic flux through the loop is changing. The
direction of the induced current is such that the induced magnetic
field opposes the change in the flux. The following Tactics Box
summarizes the essential steps in using...

Question 1 Select the correct answer(s): When considering electromagnetic induction, Lenz's Law determines the magnitude of the emf induced across the ends of a coil of wire that is rotating in a magnetic field. The smaller the change in magnetic flux, the greater the induced emf. Faraday's Law can be used to calculate the magnitude of an induced emf. Electric current can be induced by a changing magnetic field. Submit Answer Tries 0/3

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...
