Which of these is correct?
Which of these is correct?
A wire carries a current, creating a magnetic field around itself as shown. The current in the wire is:
Directed to the right
Directed to the left
Equal to the magnetic field
In the same direction as the magnetic field
The magnetic field inside the coil shown below is directed:
Into the page
Out the Page
To the left
Towards the bottom of the page
In the figure, using the right hand rule around a solenoid, which of the below statements is correct:
North Pole is 7 and South pole is 8
North Pole is 8 and South Pole is 7
There is no magnet, so no north or south
The current is flowing in the direction from 7 to 8
Two parallel wires are separated by 40 cm. If the current in the second wire is twice the current in the first one, what happens to the wires?
The magnetic force causes a repulsion between wires
The magnetic force causes an attraction between the wires
What is this the definition for: a wire of length 1m carrying a current of 1A at a right angle to the magnetic field experiences a force of 1N.
(a)
Two long, parallel wires each carry the same current in the same direction. What is the total magnetic field at the point midway between the wires?
Zero
Directed into the page
Directed out of the page
Directed to the left
Solenoid 1 has a length L, cross-sectional area A, and N turns. Solenoid 2 has a length 2L, cross-sectional area 2A, and 2N turns. Which solenoid has the greater magnetic field at its centre when equal currents are going through them?
1
2
Both have the same magnetic field.
Since it depends on the values of A and L, none of the above are correct
Which of these equations shows the force on an individual charged particle?
F=Bqvsinθ
F=BIlsinθ
B=μonI
