The magnetic lines of forces are referred to as flux just as in a natural magnet, the field is strongest near the wire and diminishes as the distance from the wire increases the relationship between magnetism and the electric current for various shapes of current carrying conductor is given below. A magnetic field is a vector field that describes the magnetic influence of electrical currents and magnetized materials in everyday life. Write the (real) electric and magnetic fields for a monochromatic plane wave of amplitude eo, frequency ï‰, and phase angle zero that is (a) traveling in the negative x direction and polarized in the z-direction (b) traveling in the direction from the origin to the point (1,1,1), with polarization parallel to the xz plane.
About why magnetic field was denoted as b i recall that maxwell just used the letters a through h for vectors in his treatise on electricity and magnetism and some of them stuck and a is still used for vector potential, b for magnetic field (or magnetic induction or flux density, depending who you ask. Question when a car drives through the earth's magnetic field, an emf is induced in its vertical 720cm -long radio antenna if the earth's field (50×10-5t) points north with a dip angle of 47 degrees, what is the maximum emf induced in the antenna and which direction(s) will the car be moving to produce this maximum value. Magnetic field strength is specifically a quantification of the strength of a magnetic field, and this is effectively given in units called teslas denoted by letter t, the standard element for magnetic field strength contact us for magnetic field strength assignment help.
In my following coursework, i will carry out an investigation on a variable, which affects the strength of an electromagnet i tend to also create an accurate enough analysis, which will help me determine why the variable investigated, affected the strength of the electromagnet. In a magnetic field, where is it strongest where the field lines are closest together what is a solenoid the movement of electrons within the atoms of the magnet each electron represents a tiny current as it circulates within its atom, setting up a magnetic field. When writing, the magnetic medium is heated locally by a laser, which induces a rapid decrease of coercive field then, a small magnetic field can be used to switch the magnetization the reading process is based on magneto-optical kerr effect. Magnetic field (solved) march 29, 2012 in the figure below , two long straight wires are perpendicular to the page and separated by a distance d 1 = 080 cm wire 1 carries 57 a into the page. Magnetic field: the space around a magnet in which a net force acts on a magnetic test pole is known as magnetic field or the space around a magnet in which a torque acts on a magnetic needle is known as a magnetic field.

Magnetic field i introduction everybody uses magnetic forceswithout them there would be no electric motors, tv picture tubes, microwave ovens the most familiar aspects of magnetism are those associated with permanent magnets, which attract unmagnetized iron objects and can attract or.
Our magnetic fields lab was helpful in the visual understanding of the formulas we have been leaning in class we were able to map the magnetic field lines for the purposes of understanding how magnetic fields react when fields combine, as well as finding the null point as a result of those fields interacting. Magnetic fields writing assignment topics: earth's magnetic field, magnetic field, magnet pages: 1 (380 words) published: january 26, 2014 10/13/13 physics 202-3 the magnetic fields we observed in the first exercise were really well defined by the metal filings sprinkled onto the paper. To write magnetic data, current is sent through the coil in proportion to the desired signal this current produces a magnetic field proportional to the current this reading assignment has only touched on the applications of magnets in information systems and other commonly-used technologies. Magnetic fields magnetism is closely related to electricity magnets are polarized, meaning every magnet has two opposite ends the end of a magnet that points toward the geographic north pole of the earth is called the north pole of the magnet, while the opposite end, for obvious reasons, is called. Sources of magnetic field assignment is due at 2:00am on wednesday, march 7, 2007 credit for problems submitted late will decrease to 0% after the deadline has magnitude of the magnetic field the biot-savart law, which gives the magnetic field produced by a moving charge, can be written.

(4) pole strength (m) : the strength of a magnetic pole to attract magnetic materials towards itself is known as pole strength (i) it is a scalar quantity (ii) pole strength of n and s pole of a magnet is conventionally represented by +m and -m respectively. Motors use magnetic fields to rotate a shaft as the electric current going to the motor varies--all later a loop of wire is rapidly moved past the spot and the field from the magnetized spot will induce in this way information is read and recorded because the read/write device does not actually have to.
