Currents and Magnetism |
| “Oersted's experiments, using a relatively simple instrument, were enough to rock the
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. ...... Read |

Magnetic Force on a Moving Charge |
Magnetic Force on a Moving Charge
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.......................... Read |

Magnetic Force Microscopy |
| For visualisation of magnetic domains by Scanning Probe Microscopy different Magnetic Force Microscopy
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. Read |

Magnetic Fields and Magnetic Forces |
| Magnetic fields are created by charges in motion (currents)
• 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
only acts on charges in motion Read |

CIVIL ENGINEERING |
| The accredited program in Civil Engineering prepares graduates to enter
the profession in planning, design, construction, operations, or
management capacities on such projects as freeways, highways, major
buildings, dams, bridges, aqueducts, pipelines, airports, hydro-electric
installations, water treatment plants, sewage treatment plants, flood
control works, and urban development programs. The department offers
three options: the general civil engineering option; the environmental
engineering option; and the geospatial engineering option, all of which
are accredited by ABET. Read |
