A unit of magnetic induction is:

Correct answer: A. Weber/metre2

  • A. Weber/metre2
  • B. Weber/ampere-metre
  • C. Weber/metre
  • D. Weber

Explanation

Option A is correct. The unit of magnetic induction is Tesla or Weber per metre2. Magnetic induction (B) describes the magnetic field's strength and direction, measured in Tesla (T). The relationship can be expressed as: 1 T = 1 Wb/m2. Option B is incorrect because Weber/ampere-metre refers to magnetic field strength (H), not magnetic induction (B). Option C is incorrect as Weber/metre does not correctly define the magnetic induction unit, which needs to involve area. Option D is also incorrect because Weber alone measures magnetic flux and does not account for area, which is essential for magnetic induction.

About Electromagnetism

Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
