Question

The region surrounding a magnet, where the magnetic force can be detected, is said to have

• A. Electric field
• B. Magnetic vortex
• C. Magnetic field
• D. Electric vortex

Hint:

A field is a region of space where a force is felt:
- Mass feels force \(\to\) Gravitational field.
- Charge feels force \(\to\) Electric field.
- Magnet/moving charge feels force \(\to\) Magnetic field.

Answer 1

The Correct Option is C

Step 1: Understanding the Question:
The question asks for the definition of the physical region surrounding a magnet in which its magnetic influence or force can be experienced by other magnetic materials or moving charges.

Step 2: Key Formula or Approach:
By definition, a field is a region of space where a force is exerted on an object. For magnetic forces, this space is called the magnetic field.

Step 3: Detailed Explanation:

• A magnet influences the space around it. When another magnetic pole (such as a compass needle or iron filings) is placed in this space, it experiences a magnetic force.

• This space or region of influence is scientifically termed as the magnetic field.

• The magnetic field is a vector quantity, having both magnitude and direction.

• It is represented geometrically by magnetic field lines, which emerge from the North pole and enter the South pole outside the magnet.

• Other options like "magnetic vortex" or "electric vortex" are not standard scientific terms used to describe this basic field phenomenon.


Step 4: Final Answer:
The region is said to have a magnetic field.
