Question

The pole faces of a permanent magnet as shown in the figure. A wire of length 4 cm carrying a current of 10 A is placed in the central region, where the magnetic field is 0.2 T. The magnitude of the force on the wire is​

Answer 1

The magnitude of the Magnet would be 0.08 N.

Magnetic Field:

• Magnetic Field is the domain about a drawing material or a exciting energetic charge inside that extrasensory perception of attractiveness acts.
• A magnetic field of currents is a heading field in the neighbourhood of a bait, energetic current, or changeful energetic field at which point attractive forces are apparent. A magnetic field of currents is presented by affecting energetic charges and basic attractive importance of basic atoms guide a fundamental quantity possessions famous as spin.
• Magnetic field and energetic field are two together pertain and are parts of the electromagnetic force, individual of the four fundamental forces of type.
• The magnetic field of currents maybe mathematically interpreted as a heading field. The heading field is a set of many headings that are tense on a gridiron. In this case, each heading points in the route that a compass would point and has a distance weak on the substance of the drawing force.
