When you demonstrate the magnetic field of a bar magnet using iron filings, the filings form lines. But isn’t the field a continuous plane? What makes the lines form and why do they spread apart at ...

The concept of magnetic field lines and magnetic fields was first studied and observed by Michael Faraday and by James Clerk Maxwell, who made great discoveries in the field of electromagnetism.

THE name of Faraday will go down to posterity foremost amongst the names of the scientific men of this century, for the simple comprehensiveness and original beauty of his researches in electricity ...
