Concave pole faces of the magnet and soft iron cylinder in galvanometer are used to make the field
Correct answer: D. radial and stronger
- A. strong
- B. weak
- C. radial
- D. radial and stronger
Explanation
The concave pole faces of a magnet and a soft iron cylinder in a galvanometer are configured to affect the magnetic field within the instrument.he concave pole faces are engineered to not only produce a focused or concentrated magnetic field but also to ensure its strength. Therefore, they tend to create a magnetic field that is both more concentrated and stronger.Possible Correct Answer:(d) radial and stronger

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.
