The direction of the magnetic lines of force can be found by using:
Correct answer: A. Right hand rule
- A. Right hand rule
- B. Henry's law
- C. Left hand rule
- D. Faraday's law
Explanation
The right-hand rule is specifically designed to find the direction of the magnetic field created by a current-carrying wire. By pointing your thumb in the direction of the current flow, your fingers naturally curl in the direction of the magnetic field lines. This is different from Henry's law, which pertains to gas solubility, and Faraday's law, which discusses electromagnetic induction. Similarly, the left-hand rule is used to determine the direction of force in a magnetic field, not the magnetic field itself.

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.
