Chapter 36, Problem 29A

Since iron filings are not themselves magnets, by what mechanism do they align themselves with a magnetic field as shown in Figure 36.6?

To determine

To explain: The mechanism with the help of which iron align themselves with a magnetic field

Explanation of Solution

Introduction:

The magnetic field is that field which is induced by the moving charged particles. Iron filings are the ferromagnetic substances. According to the definition of ferromagnetic substances, these are those substances that align themselves in the direction of the magnetic field.

The cluster of aligned atoms in the fillings is produced into alignment in the direction of external magnetic field lines. Due to which poles are produced in the iron filings, then they are acted on by the external magnetic field which results in the torque on each iron filling. Due to the resulting torque, a couple is produced which aligns the filing with in the direction of themagnetic field.

Conclusion:

The electric field is produced surrounds the stationary charged particle but the electric field as well as magnetic fields is also produces surrounds the moving charged particles.
