The national high magnetic field laboratory holds the world record for creating the strongest magnetic field. their largest hybrid magnet can produce a constant magnetic field of 45 t. to see if such a strong magnetic field could pose health risks for nearby workers, calculate the maximum acceleration the field could produce for na* ions (of mass 3.8 times 10-26 kg) in blood traveling through the aorta. the speed of blood is highly variable, but 35 cm/s is reasonable in the aorta. would you guess that the acceleration you found above would be dangerous for workers to be near such a large magnetic field?

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

You can decrease the resistance of a length of wire by

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14πϵ0. d)the ball will oscillate along the z axis between z=d and z=−d in simple harmonic motion. what will be the angular frequency ω of these oscillations? use the approximation d≪a to simplify your calculation; that is, assume that d2+a2≈a2. express your answer in terms of given charges, dimensions, and constants
