Question

*Which scientist explained that magnetic force lines must have certain properties?*

1️⃣ Newton
2️⃣ Benjamin Franklin
3️⃣ Michael Faraday
4️⃣ Democritus​

Answer 1

Answer:

Michael Faraday

The concept of lines of force was introduced into physics in the 1830s by the English scientist Michael Faraday, who considered magnetic and electric effects in the region around a magnet or electric charge as a property of the region rather than an effect taking place at a distance from a cause.

Answer 2

Michael Faraday explained that magnetic force lines must have certain properties.

• Michael Faraday was one of the greatest scientists of his era who gave major contribution in the field of electricity and magnetism.
• He proposed that electric charges as well as magnets produce lines of force.
• These lines of force reveal the direction of the force.
• They have certain specific properties like they are closed curves, do not intersect each other, etc
