Did you know?
WebA magnetic field is defined as: The region around a magnet where a force acts on another magnet or on a magnetic material (such as iron, steel, cobalt and nickel) Magnetic Field Lines Magnetic field lines are used to represent the strength and direction of a magnetic field The direction of the magnetic field is shown using arrows Webθ = angle between magnetic field lines and the line perpendicular to the plane of the area (often called the normal line) (degrees) This means the magnetic flux is: Maximum = B A when cos ( θ) = 1 therefore θ = 0 ∘. The magnetic field lines are perpendicular to the plane of the area Minimum = 0 when cos ( θ) = 0 therefore θ = 9 0.
