Questions & Step-by-Step Solutions

If a magnetic field is applied perpendicular to a loop of wire, what is the effect on the induced EMF?
  • Step 1: Understand what a magnetic field is. It is an invisible field that exerts a force on charged particles and magnetic materials.
  • Step 2: Know what a loop of wire is. It is a closed circular path made of conductive material through which electric current can flow.
  • Step 3: Learn about magnetic flux. It is the amount of magnetic field passing through a surface, like our loop of wire.
  • Step 4: Recognize that when a magnetic field is applied perpendicular to the loop, it means the field is directly entering or exiting the loop.
  • Step 5: Realize that this perpendicular position maximizes the magnetic flux through the loop because the entire area of the loop is exposed to the magnetic field.
  • Step 6: Understand Faraday's law of electromagnetic induction, which states that a change in magnetic flux through a loop induces an electromotive force (EMF) in the loop.
  • Step 7: Conclude that since the magnetic flux is maximized when the field is perpendicular, the induced EMF will also be at its maximum.
  • Faraday's Law of Electromagnetic Induction – The principle that an electromotive force (EMF) is induced in a circuit when there is a change in magnetic flux through the circuit.
  • Magnetic Flux – The product of the magnetic field strength and the area of the loop perpendicular to the field, which determines the amount of magnetic field passing through the loop.
  • Induced EMF – The voltage generated in a conductor due to a change in magnetic flux, which can be maximized by the orientation of the magnetic field.
