A scalloped hammerhead shark swims at a steady speed of 1.0 m/sm/s with its 83 cm -cm-wide head perpendicular to the earth's magnetic field.
What is the magnitude of the emf induced between the two sides of the shark's head?
Express your answer using two significant figures.
Answer & Explanation
The velocity of hammerhead shark
Length of hammerhead .
the magnetic field of the earth
the angle between the hammerhead and the earth's magnetic field .
the magnitude of electromotive force is given by,
- The speed of scalloped hammerhead shark is: .
- The width of head is: .
- The magnetic field is: .
The expression for the change in area through which magnetic field moves is,
Here are change in length and width respectively.
The expression for the speed of scalloped hammerhead shark is,
Here is time interval.
The expression for the magnetic flux is,
The expression for the induced emf by using the Faradays
Answer: . Explanation: Emf induced Where B is magnetic field , L is length of rod or any other object moving in magnetic field and v is velocity of moving rod. Here emf induced .
