(i)The electric field lines representing the induced electric field form closed contours. §21.1 Faraday’s law of electromagnetic induction (ii)The static electric field arises from stationary electric charge, the induced electric field is produced from changing magnetic flux. 4. The characters of the induced electric field 1The static electric field lines do not form closed loops, they begin on positive charge and end on negative charge. But the induced electric field lines form closed loops, it means that the flux of the induced electric field through any closed surface is zero. 2The electric force produced by the induced electric field is not a conservative force! The work done by the electrical force due to the induced electric field around a closed path is not zero. §21.1 Faraday’s law of electromagnetic induction ⋅d = 0 ∫ E s r r ⋅d ≠ 0 ∫ E l r r
