Two parallel wires carrying currents in opposite directions with proton moving?

Question

Two long parallel wires carry equal currents in opposite directions. (up and down the page, respectively) Wire 1 is to the left of Wire 2 and its current is downwards. Wire 2 has current in the upward direction. Where would a proton moving at a speed of 2 X 10^5 m/s experience a maximum force?

a. between the two wires, moving left towards wire 1
b. to the left of wire 1, moving left
c. between the two wires, heading into the page

Thanks!

Answer 1

Well, since the current in the wires are in opposite directions, the magnetic field halfway between the two wires are in opposing directions, so a proton heading into the page halfway between the two wires will not experience any force, so the answer is NOT c)

If the proton is moving away from the wire on the left will experience a decreasing force, so b) is NOT the answer.

a) is the answer since the proton is moving perpendicularly to the magnetic field and is heading into a stronger magnetic field as it approaches wire 1.

Answer 2

considering a magnetic field is produced round a cord carrying a replacing modern-day then each will produce a field of opposite polarity. considering those are identically opposite then the consequent field will be 0. for this reason no longer something takes position except the wires get hotter. If the present is intense adequate then the wires might want to soften till a protecting device disconnected the wires from the flexibility source. If a surge of intense modern-day passes by ability of the cord and no restraint is in position then they could 'snake' about in an unpredictable way and can want to sever because of mechanical and thermal forces. If the present is consistent then a magnetic field isn't produced although the wires might want to nonetheless behave in the different case interior an same way because the equipment of a replacing modern-day.

Answer 3

The magnetic force is charge times velocity cross magnetic field. So the strongest force is when it is moving perpindicular to the field.

To figure the field itself, put your RIGHT thumb in the direction of the currents and let your fingers wrap around to show you the field direction.

So figure out where the fields are strongest (adding up instead of canceling). Which of the three options has the proton moving across the field at its strongest point?????

Answer 4

Protons do not carry current. They are found in the nuclei of atoms, are you asking about electrons?
