How can we increase the strength of magnetic field of solenoid? Strength of a Solenoid Adding more turns to the coil of wire increases the strength of the field. Increasing the amount of current flowing through the coil also increases the strength of the magnetic field. What is solenoid mention two ways to increase? Two […]

How do you activate the ciliary muscles? Activation of the M3 muscarinic receptors, acetylcholine receptors that are formed by G-protein complexes, trigger the contraction of the ciliary muscle and reduce the diameter of the ciliary muscle ring. Contraction allows the zonular fibers to relax and the lens becomes more spherical to improve near vision. What […]
