Yes you can, it is actually very easy to steep them too long. If you leave the tea leaves in the tea too long they begin to release a harsh bitter flavor that no one wants. The best way to make your tea stronger is to add more tea leaves not more time. Below I have listed a small list of the average time it takes to steep each type of tea.
Currently, physicists describe nature as having 4 fundamental forces: the Electromagnetic force, the Strong nuclear force, the Weak nuclear force, and the Gravitational force. At one point in history, the Electric and Magnetic fields were treated as separate. If you count these two fields as separate and add them to the other 3 traditional force fields -- the Gravitational, Strong, and Weak fields -- then, nature might be described as having a total of 5 fundamental fields in Physics.
Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from the Earth 's interior to where it meets the solar wind, a stream of charged particles emanating from the Sun.ts magnitude at the Earth's surface ranges from 25 to 65 microteslas (0.25 to 0.65 gauss). Roughly speaking it is the field of a magnetic dipole currently tilted at an angle of about 10 degrees with respect to Earth's rotational axis, as if there were a bar magnet placed at that angle at the center of the Earth.
