A freely suspended magnet will always point in the North - South direction in the absence of any other magnet. This suggests that the earth itself behaves as a magnet which causes a freely suspended magnet (or magnetic needle ) to point always in a particular direction namely North and South.
The south pole of the earth's magnet is in the geographic north because it attracts the north pole of the suspended magnet and vice versa. However it is important to note that the position of earth's magnetic poles are not well defined because they are spread over an area.
The doctor or nurse will ask a urine sample of the daughter for lab analysis to check for bacteria, red blood cells or white blood cells. Sometimes after the urine lab analysis it will be followed by a urine culture. This test will tell the doctor what kinds of bacteria are the source of the infection and which treatment or medicine will work the most. If the daughter is having frequent infections or low grade fever that the doctor concludes that it may have been caused by an abnormality in the urinary tract, she may have a magnetic resonance imaging (MRI), a computerized tomography (CT) scan or ultrasound. The doctor or nurse may use a contrast dye as well to highlight structures in the child’s urinary tract. Moreover, the doctor may conduct a cystoscopy, using a long, thin tube with a lens (cystoscope) to see inside the child’s bladder and urethra if the child will have recurrent UTIs.
