Magnetic field

Magnetic Field Therapy Danielle Scott Vermont Technical College Magnetic Field Therapy Magnetic field therapy should be used as a complementary and alternative medicine before pharmaceutical interventions to treat patients. Magnetic field therapy penetrates the entire body and has fewer side effects. Magnetic field therapy has many benefits to offer patients to maintain health and treat illness. Magnetic field therapy provides a non invasive, safe, and easy method. The physiological bases for the use of magnetic fields for tissue repair as well as physical principles of dosimetry and application of various magnetic fields. Dr. Pawluk 's (2016). philosophy is our legacy prior to and after this physical existence is much grander…

a) According to the right-hand rule, the direction of the magnetic fields of the 3 wires are shown: We find the magnetic fields B1, B2 and B3: 퐵1=퐵2= 푢0 푖 = 푢0 푖 = 4∗3.14×10−7 ∗(3.65) =ퟒퟐ.ퟔퟔퟎ풖푻 2휋푟 2휋( 2푎) 2 ∗ 3.14 ∗( 2(0.0121)) 퐵3= 푢0 푖 = 푢0 푖 = 4∗3.14×10−7 ∗(3.65) =ퟐퟎ.ퟏퟏퟎ풖푻 2휋푟 2휋(3푎) 2 ∗ 3.14 ∗(3∗(0.0121)) The x components of the B1 and B2 cancel each other; therefore the net magnetic field will be downward and we have (the negative sign is because the direction is downward): 퐵=− 퐵1cos 45 +…

Field strength or intensity is the force which maintains the magnetic flux and produces a particular value of the flux density B at that point in a magnetic field. Therefore the flux density is the cause while the flux density (B) is the effect. The flux density can be assumed proportionally to the field intensity in a magnetic field which comes in three parts. First part is: Where U stands for the permeability of force (the measure of the degree to which the magnetic line of force can…

mechanical devices applied in daily life activities are powered by electric motors. Motors transform electrical energy to mechanical energy, hence they are essential for energy conversions in electrical machines. All types of electrical motors are made up of a stationary field referred to a stator and a rotating field referred to a rotor. According to Krishnan, (2010), DC motors operate through the interaction of an electric current with magnetic flux to generate a torque and rotational speed.…

there is a whole chapter on the nature of induced forces in magnetic fields. This struck great interest and lead to further research. In the 1830’s, an English scientist named Michel Faraday was credited with the discovery of induced currents and the practical behind it. He first wrapped a copper wire around an iron ring. On one side of the ring, there was a battery with a switch. On the opposite side, there was a galvanometer. He noticed a strange pattern in variations in currents. This…

Magnetic therapy or magnet healing is a type of alternative medicine that have magnetic fields that generates healing powers towards a large number of diseases or conditions. These electromagnetic fields have been demonstrated to treat slow-healing fractures in the body and have shown good results towards to a few conditions. The website that has claimed to use this magnetic therapy are Skepdic.com. The claim that this complementary and alternative medicine practitioner is making goes…

Brushless DC Motor Physics Report. Isaac Mills. Motor: A machine powered by electrical current or the explosion of gases inside chambers that will provide movement for a vehicle. When an electric current, magnetic field or external force acts on a coil found inside of the motor, it will provide force to it, thus causing the coil to move, the coil rotates on a half turn basis otherwise the motor is forced to stop and will not move. The Motor Effect Motor effect refers to a current carrying…

the approximate amount of work a strong dray horse could do while lifting coal for one minute (The Editors of Encyclopædia Britannica, n.d). It is, therefore, reasonable to assume that a human could do 67% of this amount of work for a shorter amount of time. Generator What would happen to the force required to turn the generator if the bulb was taken out? Why? Of the bulb was taken out of the generator then the amount of work required to turn the generators handle would be decreased because…

through the day. These auroras are caused by charged particles that collide with the magnetic atmosphere. At first glance the aurora looks to be light in colour but the substorm after the first glow is a lot brighter and has a much darker colour. Yusuke Ebihara is a physicist from Japan who has been studying these northern lights. He and his partner, Tanaka, used a computer to create many different sequences…

Maxwell and Faraday- A Brief History of Electromagnetism The field of electromagnetism was established in 1819, twelve years before Maxwell was born. Hans Christian Oersted from Denmark was the first scientist who thought of the possibility that magnetism and electricity were related. He considered such a possibility because of the observations he made during an experiment. He Placed a wire above a compass and passed a current through the wire. He noticed that the needle of compass moved when…
