Question

Define a solenoidal vector field. A is not conservative.

Answer 1

the solenoid is a long coil containing a large number of close turns of insulated insulated copper wire. the magnetic field produced by a current carrying solenoid is similar to the magnetic field produced by a bar magnet .

the strength of magnetic field produced by a current carrying solenoid depend on .

1.the number of terms in the solenoid. large and the number of turns in a solenoid greater will be magnetism produced .

2.the strength of current in a solenoid. larger the current pass through the solenoid is stronger will be magnetic field produced .

3.the nature of core material used in making solenoid the use of soft iron rod as a call in the solenoid produce the strongest magnetism .

Answer 2

Explanation:

$\huge \mathtt \pink{ \xcancel{d B = \frac { M _ { 0 } n d x I a ^ { 2 } } { 2 [ ( r - x ) ^ { 2 } + a ^ { 2 } ] ^ { 3 / 2 } }}}$
