Two straight, long and thin parallel wires are spaced d=0.1m apart and each, carry a current of 10A. A point P is located at a distance d from both the wires. Find the magnetic field at P when(a) both the wires have current in the same directions.(b) both the wires have current in the opposite directions.

A particle having charge q=10μC is moving with a velocity of v=106m/s in a direction making an angle of 45∘ with positive x axis in the xy plane (see figure). It experiences a magnetic force along negative z direction. When the same particle is projected with a velocity v′=106m/s in positive z direction, it experiences a magnetic force of 10mN along X direction. Find the direction and magnitude of the magnetic field4∘⟶xin the region.

The flux density and link equation can be used to calculate the power received by an earth station from a satellite transmitter with output power P (W) and driving an antenna with gain Gt. The flux density (W/m^2) in the direction of the antenna bore sight at a distance r meters on earth is given by:P * Gt / (4 * π * r^2)Power densitySatellite AntennaDownlinkEarth Station Antenna (Receiving)Terrestrial system (low-noise receiver)Output (User)Path loss between satellite antenna and ground station is the algebraic sum of various loss components such as losses in the atmosphere due to attenuation by air, water vapor, and rain, losses at the antenna at each side of the link, and possible reduction in antenna gain due to antenna misalignment.Explain why power density and path loss are important factors in satellite link calculations? (12 marks)A satellite downlink at 10 GHz operates with a transmit power of 20 W using an antenna with directivity of 48 dB and 90% efficiency. Calculate the Effective Isotropic Radiated Power (EIRP) in dBW. State why EIRP is an important figure of merit in satellite link design. (12 marks)A satellite operating at 10 GHz at a distance of 39,000 km radiates 20 W of power from an antenna with a gain of 25 dB in the direction of a satellite terminal with an effective aperture area of 10 m^2. Find the flux density at the earth station location and the power received by the satellite terminal antenna. (9 marks)
