An electromagnetic flow meter applies a magnetic field of $0.20 \mathrm{T}$ to blood flowing through a coronary artery at a speed of $15 \mathrm{cm} / \mathrm{s} .$ What force is felt by a chlorine ion with a single negative charge?

Key Concepts

Electric Charge

Electric charge is an intrinsic property of particles that determines their electromagnetic interactions. In the context of the Lorentz force, the magnitude and polarity (positive or negative) of the charge influence both the force's magnitude and its direction when the particle moves through a magnetic field.

Lorentz Force

The Lorentz force is the force exerted on a charged particle moving through an electromagnetic field. It is calculated using the equation F = qvB sin(?), where q is the particle's charge, v its velocity, B the magnetic field, and ? the angle between the velocity and the magnetic field vectors. This force is perpendicular to both the velocity and the magnetic field, dictating the particle's motion.

Magnetic Field

A magnetic field is a region where magnetic forces are exerted on moving charges and magnetic dipoles. Represented by the vector B and measured in tesla (T), it influences the magnitude of the force acting on a moving charge. Its orientation and strength are key in determining how charged particles behave in its presence.

Velocity

Velocity refers to the speed and the direction at which a particle moves. In the Lorentz force equation, the speed of the moving charged particle influences the magnitude of the force; only the component of the velocity perpendicular to the magnetic field contributes, making the directional relationship crucial.
