No.
Because that is not how comets act.
The one portion of that v is facing away from us.
And the pieces of an object that is tidally disrupted tend to continue down the same orbit.
Shoemaker-levy 9 is an example of that.
It had been orbiting Jupiter and then tidally disrupted.
The pieces had two years to spread out.
The spread into a straight line.
Magnetic field lines wouldn’t do anything to the comet.
The field lines resemble a coil watch spring.
If the comet reacted to that, you’d see a smear resembling a paintbrush stroke following an arc from where it is at back in a huge curve towards the sun.
Instead, what was left of ison prior to fading out behaved like a typical comet.
Dust trail along orbit, tail pointing away from the sun.
