To examine the effect that magnetic fields have on moving charges.

To examine the magnetic field produced by a long, straight current-carrying wire.

foundations of Newtonian Mechanics. The nature of magnetic force was distinct

from the forces known until then. It was certainly not a central force, since it was

not oriented along a straight line between two interacting points, as happens with

gravitational forces, interacting forces between electrical charges at rest, or between

the two poles of a magnet. ......

Electric charges moving in a magnetic field experience a force due to

the magnetic field.  Given a charge Q moving with velocity u in a magnetic

flux density B, the vector magnetic force Fm

 on the charge is given by..........................

probes are offered. They are designed to match the demands of a wide range of applications defined by the 

variety of magnetic samples with different properties. All the different magnetic coatings of the probes have 

proven an excellent long-term stability.

•  Magnetic fields are denoted with the symbol B. 

•  Electricity & magnetism are related (relativity is the bridge) 

•  Magnetic fields are force fields like electric fields but the magnetic force

about $850 million at the box office world-wide, 

and is expected to pass $1 billion, topping the 

"Jurassic Park" record of $930 million in 1993; 

studios get about half the box office. Production 

costs alone were more than $200 million.

Paramount, a unit of Viacom Inc. "capped" its 

investment in the film at $65 million; Twentieth 

Century Fox, a News Corp. unit, had to pay that 

amount, plus pick up the tab when "Titanic" went 

at least $80 million over its $120 million budget.

1912, she was hailed as ‘the new wonder of the world’. A remarkable 

feat of engineering, she was the largest and most luxuriously 

appointed ship ever seen and, despite her tragic sinking five days 

later, she remains a source of enduring pride in the City where she 

was built – Belfast.
