Question

Question 1 2 pts How will the magnetic domains in an unmagnetized "soft" iron rod respond to the presence of a strong external magnetic field? The domains will tend to align with the external field. The domains will split into monopoles. The domains will tend to orient themselves perpendicular to the external field, The domains will tend to align so as to cancel out the extemalfiel The domains will not respond to an external magnetic field

Answer 1

Dear student,

Find this solution, and RATE IT ,If you find it is helpful .your rating is very important to me.If any incorrectness ,kindly let me know I will rectify them soon.

Thanks for asking ..

1) If a ferromagnetic material ( softison) is placed inside the external magnetic field then all domains alligned in the direction of applied field. option (a) is correct.) And 2 ) Force (F) = BIl sino force is zero, if 0 = 0 or 1 so (parallel) option (a) is correct) And 3) N=150, V-IV, Magnetichield is produced in the Solenoid. So, Itis an electromagnet.) optim(a) [8 Coved IN 4) Proton is a positive charge Pq1Dx2) so force will come "out of the page (towards the option (a) is correct EA
