Question

The field of a solenoid is most like the field of a: long, straight wire single bar magnet horseshoe magnet single pole

Answer 1

Single bar magnet

Step-by-step explanation:

As we know that magnetic field of solenoid inside the solenoid is strong and given by formula

`B = (\mu_0 N i)/(L)`

here we know

L = length of solenoid

i = current in the coil

now as we observe the field outside the solenoid the magnetic field will start decreasing as we go far away from the end.

so strength of magnetic field will be more near the end and start decreasing as we move away from it

this all characteristics are similar to the magnetic field of a bar magnet

so this solenoid is similar to a bar magnet
