# An electric current in a wire creates a circular magnetic field around the wire, its direction ( clockwise or counter-clockwise ) depending on that of the current.

# A current is induced in a loop of wire when it is moved towards or away from a magnetic field, or a magnet is moved towards or away from it, the direction of current depending on that of the movement.

# Recordings ( gramophone records, magnetic tapes, cassettes, cartridges, CDs, DVDs ) from the late 19th century

# Electric currents or more generally, moving electric charges create magnetic fields ( see Maxwell's Equations ).

# Many particles have nonzero " intrinsic " ( or " spin ") magnetic moments.

# The field confining the Earth's plasma and magnetic field inside the magnetospheric cavity.

# If all the particles are identical ( same energy barrier and same magnetic moment ), their easy axes are all oriented parallel to the applied field and the temperature is low enough ( T < sub > B </ sub > < T ≲ KV /( 10 k < sub > B </ sub >)), then the magnetization of the assembly is.

# The local strength of the magnetic field of the Earth.

# changes in a magnetic field structure to that an open topology, leading to a decrease of magnetically confined plasma, or

# changes in the magnetic dynamo character, leading to the disappearance of stellar fields leaving only small-scale, turbulence-generated fields among red giants.

# The magnetic induction field B is given in SI units of teslas ( T ).

# The magnetic field H is given in SI units of ampere-turns per meter ( A-turn / m ).

# Hall coefficient ( electrical physics )-Relates a magnetic field applied to an element to the voltage created, the amount of current and the element thickness.

# magnetic drums

# Falling droplets of ice and rain become electrically polarized as they fall through the earth's magnetic field ;

# For a circuit consisting of an electrical generator that drives current through a resistor, the emf is due solely to a time-varying magnetic field that generates an electrical voltage that in turn drives the current.

In the context of magnetic fusion energy, cyclotron radiation losses translate into a requirement for a minimum plasma energy density in relation to the magnetic field energy density ( see Aneutronic fusion # Power density and energy balance ).

# An electric current passes through a solenoid, resulting in a magnetic field.

# Magnetic poles ( or states of polarization at individual points ) attract or repel one another in a similar way and always come in pairs: every north pole is yoked to a south pole.

# If the design is symmetrical in an axis parallel to the flag pole, obverse and reverse will be identical despite the mirror-reversal, such as the Indian Flag or Canadian Flag

# A freestanding vertical pole on a base.

# Begin with a clove hitch on the vertical pole beneath the horizontal pole and tuck the loose end under the wrapping.

# Wrap in a square fashion ( behind the back pole, over the front pole, etc.

# Tie two half hitches around the horizontal pole

# Begin by placing the middle of the rope under the bottom pole

# Lay both ends over the top pole, and cross under the bottom pole.

# After the last wrap, cross the ropes again over the bottom pole and frap around the wrappings.

# Mobilize the superior pole of the thyroid lobe.

# f has a pole of some sort at x, so is not even defined at x, as for example a rational function, which would be defined off a subvariety.

He had four sons who also were skilled pole vaulters ; Brandon, held the national high school record at 18 ' 2 " for fourteen years from 1985 ; Tom won the CIF California State Meet in 1988 ; Bob, Junior was second in the same meet in 1968 and later ranked # 7 in the USA in 1973.
