Magnetic field induction due to an infinite long solid cylindrical conductor of radius R at a distance x< R and y>R are equal in magnitude then :
Correct answer: A. xy=R2
- A. xy=R2
- B. xy=R
- C. x=y
- D. x/y =R
Explanation
x > R , B = (μ₀ / 4π) · (2I / x)y < R , B′ = (μ₀ / 4π) · (2I y / R²)But B = B′⇒ xy = R²

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
