Answer: a magnetic field is created by moving electric charges
Answer:

According to the Fleming's Left left hand rule we have higher potential on the right edge of the wing.
Explanation:
Given:
- velocity of plane,

- magnetic field,

- angle between velocity and magnetic field,

- span of the wing,

We know:



According to the Fleming's Left left hand rule we have higher potential on the right edge of the wing.
Produce power through the circuit.
The ball with greater mass has more density
