Please refer to this paper (http://web.mit.edu/ellisk/www/monopoles.pdf). It says in the Section B,
... One search technique relies upon the fact that, just as an electric current produces a circulating magnetic field, a magnetic current produces a circulating electric field; see equation (1). If a magnetic monopole were to pass through a conducting ring, there would be an induced current from the circulating E~ field. This current would be qualitatively different from that of an ordinary magnetic dipole passing through a conducting ring.
- How can we differentiate the effects created due to passing of (i)a monopole, (ii)a dipole, (iii)a pair of N and S poles (passing one by one along the same path) and (iv)a stream of monopoles (mixed with N and S poles)?
The circular track through which the proton beams are accelerated contains more than 1,000 very powerful magnets.
- What if these magnets can exert enough force to extract a monopole even before the beams collide?
- Does the Plastic NTD technique ensures that no other particle will get trapped by the detector?
- Is there any external magnetic field applied to direct the monopoles towards the detector?
